You may be right, but that's not the narrative. We must all turn down our air conditioners, eat bugs, wipe with one square of toilet paper, ride public transportation. Meanwhile as soon as you point out that the ones demanding individual actions don't actually walk the walk they will immediately switch to "The global warming problem is not going to be solved by individual actions."
On the other hand, most greenhouse gas emissions come from transportation and electricity. A good chunk of that is industrial but a lot of it is going to individual households. Individual actions could make a large difference. If you truly believed global warming was an existential threat to humans in the near term (Your lifetime) as many will claim, then you would be taking all of the individual actions you could, while also calling for collective action. If you won't take significant individual action without government coercion, then I'm not sure I believe you when you tell me it's an existential threat.
