There's definitely some enculturation there; they've been taught these things are desirable. I think a lot of them don't really have any aesthetic sense of their own, per se, but just think mcmansions are beautiful and desirable bc that's what the culture around them says to them at all times. Many of them don't have any experience of community, or when they did live in a community they were very brainworms about it. A lot of them are totally uncritical of cars and capitalism
I think there's just a profound amount of "what no theory does to a mf" going on at some level.
