Cities can and often are poorly designed for humans.
Building human-centric places isn’t only about density. Variety of density is good. Places where people can walk, ride bikes, and hang out with friends and family are good.
Congested 6-lane roads aren’t good, whether in cities, suburbs, or rural areas in between.
Yeah so you can give them all that, but if it's mainly inhabited by single "professionals" and couples with dogs, it can still be antisocial. At least that was my experience in grad school housing and living after in college towns. We had walking/biking centric layout, communal gyms and hot tubs, everything.
