All of those are good points. Living high density sucks.
The thing is, something has gotta give. It’s simply not possible for everybody to have a front yard and backyard and standalone dwelling. Density is likely the lesser evil.
Sounds like "no one goes there anymore, it's too crowded". Obviously the high-density places are providing something, or they wouldn't be high-density.
When I think about this I think there are two ends of this spectrum. On one end you can argue the merits of quiet detached housing on a large tract of land vs things like town housing. The other end the merits of living in an efficiency apartment vs sleeping on cardboard in a doorway.
