What are minimalist loser politics?

Take your pick:

• Everyone should live in small tightly packed apartments (bugman shit)
• Don’t eat meat
• Don’t have a car (15 minute cities)
• Eat bugs (it’s good for the environment!)
• Don’t have kids (it’s bad for the environment)
• If you have a car, make it a boring small one
• AC should be banned

All of these are loser politics that make mainstream people (aka normies) disgusted and unwilling to support leftist causes. And for good reason! Why should the working classes give up the little comfort and luxury they have, while the rich buy carbon credits to offset a transcontinental private jet trip to the ocean-side to board a mega-yacht orgy?

We have enough resources (especially when we do away with the capitalist class) to give everyone a nice house in a city that looks more like a forest because public and private transportation now happens underground. But people still have nice cars to ride out into the countryside or use on racetracks.

And so on. There are enough resources that everyone on the planet could have a lifestyle of a medium-developed Eastern European country like Czechia. And when the left starts using resources in a more rational way (no more profit motive) everything just gets nicer.

So why then do leftist pick these horrible restrictive policies?
