So, it's easy, but people don't want to do it because... they're evil?

It’s multipolar trap/ coordination problem. The costs of carbon emissions are diffuse and borne by everyone, while the costs of changing your behavior are mostly borne by you. It’s just a sad fact of life, and to solve it the only feasible way is to change the rules to making decarbonizing cheaper than continuing to use fossil fuels.

This has nothing to do with what the parent and grandparent comment was talking about, which is that carbon emissions can somehow be made without sacrificing lifestyle quality. Your comment implicitly admit that sacrifices have to be made.

I used to live in LA, spend tons of money on my car, not be able to do things because they were on the wrong side of the 405, and eat tons of low quality meat. Now I live in the Netherlands, bike or take the train everywhere, and occasionally eat high quality meat. My emissions are much, much, much lower here. I'm tired of being told how great my quality of life would be with cheaper gas and a bigger house.
