>If the only way to gain more consumption in your country is by productive labour, how do you get people to raise capital for larger projects?
There would be no such thing as 'Capital for larger projects' because infrastructure like roads, electricity, water, and the majority of housing would be owned and operated by the people collectively via the government. If those large scale projects are mismanaged through inattention or stupidity then the managers get sent off for reeducation in a punitive reeducation centre, if someone gats caught participating in graft, skimming, or any other exploitation of the collective resources they get executed. If you or you and a couple of friends want to open a restaurant, bespoke tailor shop, furniture shop, or other small business then you would be provided the basic infrastructure by the collective. If you manage to generate more value than you consume (surplus) then your group would get to keep that surplus to use for luxuries; but you would never be allowed to leverage that surplus to create a situation in which you are using 'Capital' to generate passive wealth through the exploitation of other workers.
>Will you allow landlords? Can a single landlord take their profits from one building and buy or build new buildings?
No. Nobody needs to own more than one home, and homes should never be used as a way to generate wealth, they should be used as homes. The average citizen, once they leave their parents home, would be entitled to a tiny bachelor pad with a bar fridge, hot plate, toilet, and shower with access to communal baths, full scale kitchens, and common rooms. If they want to live in a 'private' space with more room then they can figure out a way to contribute more to the collective so that they are awarded more, or partner up with others to have a larger shared space with a common room, bathtub, full kitchen, studio space, etc..
>If I make a innovated way to guide people around a city could someone richer buy that from me? Suppose they bought it from me for 307 million dollars.
If you make an innovative way to improve the lives of the collective you would be doing it using the educational facilities and resources available in the publically accessible labs, libraries, and research facilities that every citizen is entitles to use, free education in any art, trade, or scientific discipline that you put your effort into learning. You being educated enough to be able to create innovative new things is a net benefit to the collective. If you invest your life into being able to do that then you would be rewarded for what you produce in excess of what is expected of you. You would be rewarded with some money to spend on luxuries, but nobody would ever have 307 million dollars, nobody would ever be allowed to accumulate that much personal wealth because there is no way for someone to accumulate that much personal wealth without exploiting either the system or the other people in it.
>If I invested that in say minimizing online fraud to a level acceptable by a critical mass of merchants and then sold that for 1.5 Billion would I and my fellow investors get to keep a portion of that? If I took that money and invested in many different companies like a space ship company or mass producing electric vehicles that people would buy at a high enough price for me to be profitable would I get to keep most of that wealth?
Wouldn't be a thing. There wouldn't be 'online fraud' because defrauding an individual would get you sent to a hard labour camp, defrauding the government would be a death sentence, and in a Democratic Authoritarian Communist society there would be no poverty driving people to steal and no gratuitous accumulations of wealth to steal from. There literally would not be 'Investors' at the scale that you are talking about. Infrastructure would be at the level of government, space travel would be government, mass production of the fleet of vehicles used by the populace would be owed and operated by the government because nobody needs to own a private car that sits idle 90% of the time.
>Or will you only allow a specific maximum wealth?
Yes. You can 'own' a home, but that 'ownership' is really stewardship of the home while you and your family live there. Bigger and better homes would be available to those that sacrifice their time and energy to provide exceptional service to the collective or build a persistent family of some sort that builds out the space as the family grows . Someone that spends 15 years of their life becoming a cardiothoracic surgeon would have a pretty kick-ass bachelor pad in a residential building close to where they work, if they get married and have kids then they would get a family sized unit of similar quality. The dude that spends all his time outside of doing his mandated hours of labour cleaning the streets drinking and playing video games will live in the basic residential blocks. You get out what you put in, and if you put in nothing you get sent off to the punitive labour facility.
>Will your nation not reward people who risk their wealth?
People will not have personal wealth beyond their personal possessions and the quality of living quarters that they have earned through their labour for the collective. Nobody needs multiple houses, cars, etc.. The objective is to remove the ability for people to accumulate wealth so that a tiny few are 'rich' at the expense of others living in poverty.
>Maybe only your government will innovate and take risks. Do you think a government can take risks? Do you think a government can manage capital and labour without the information gained from profits and the free market setting values on labour and goods?
The capacity for Communist style Soviets of experts to manage the material, personnel, and informational resources nowadays is waaaaay better than it was during the Stalinist and Maoist revolutions. Modern Communist theorists gladly learn from the good and bad lessons of the development of Capitalism. It is a social science that uses the scientific method to constantly refine itself.
The main thing that Communism needs to do from the very beginning is to make sure that the 'leaders' are constantly afraid of the 'people', they need to always be aware that if they get caught with their hand in the cookie jar they will die. Strangle the people that want power for themselves right from the start so that the people that do get into power are people that have the best interests of the collective in mind
>Historically, humans have tried many other ways of organizing economies I'm not saying your idea can't work. It would be amazing if you found a better way than how most of the world currently works. I am saying it has a lot of problems it has to solve. I'm also saying you are unlikely to get many people with existing capital to join your new country.
All that said, I know it will never happen. Humanity is in general too selfishly self interested to be able to pull it off. Too many people would rather suffer under Capitalism on the slim chance that they might someday be a Capitalist. They will live as exploited slaves because that means that if they just get that big break they could become a master. I'm 51, both my children are so disabled that they will never have children of their own and will likely die before I do, and when I die that is the end of my family line, so I literally no longer have any real investment in the human race. I'd love to see our species crawl out of its own shit and become something greater than what we are, but I don't have any faith that we will.
>You also may have a problem of your most ambitious wanting to leave.
If a persons ambitions are to have so much more than other people that the other people suffer then I don't want them in my community anyway.
