Because my personal contribution won't change anything on the global scale but it would significantly impair my quality of life. Also because I've taken reasonable actions to reduce my footprint. Also because if we take care of the major offenders responsible for 70%-80% of the emissions there might be no need to care about the rest. I even doubt that anything would change if everyone in the developed world switches to this extreme economy. E.g. Russia burns coal and wastes hundreds of gigawatt hours to heat the atmosphere because of how their heating systems are designed. But of course it's lot easier to force me, a person who works from home, drives a hybrid car with 52MPG on average (and I rarely do more than a couple of hundreds km per month), travels couple of times per year and who installed a heat pump and a solar PV, to live with 19 degrees than to deal with Russia. It's equally easier to force me going full vegan instead of applying seemingly working solutions to reduce meat industry emissions (toilet training, seaweed diet, artificial meat in the end).
