The main issue is when you're still basically on-grid but a long ways away from everything, and depend on a car.
Though I am probably biased because I just bought a bit of land and hope to grow my own food on it. Pretty easy bike ride from the train station, though, and I work 100% remote.
If you want to remove car ownership you should try to provide an alternative that is actually better. If you want to avoid congestion, don't create a massive black hole in the center of each city that everything gravitates to.
There are many many people in the world who love cities. All the things that you hate about cities, they love.
Cities make up like 1% of the world wide land use. How about we leave this 1% of land to the people who love cities, and let the rest of the people who don't, to have the other 99%?
" it is ironic how the modern urban population that is so quick to assign blame for climate change (to car owners, carnivores), social injustice (to white men, preferably older), or simply a lack of mobile network coverage fails to understand their own contribution to the problems of a modern city."
What are you talking about? Cars ARE half the problems of a modern city. Car owners are the other half. Rip out the damn parking and put in flats. Ban cars and put in bike lanes. They're far, far more efficient, and have the added benefit of not mowing down pedestrians and boiling children.
