Most country, urbanist or not, do have wilderness, where you can live and die without people know.
You don’t need to live in the city if you dont want to. You can live off grid, and burn your own feces for heat if that is the life of your choosing. What people here are fighting for is to keep this living style is outside of cities.
Basically, city is not the place for giant emotional support vehicles. And outside traffic should not disrupt the normal form of transportation in cities, which should be dominated by public transport, walking, and efficient personal vehicles (like bike, scooters, wheelchairs, etc).
