I'll take my sprawling suburb with a big yard to grow ample food any day over a densely populated and carefully planned cityscape. With the advent of cheaper solar panels and electric vehicles, it's not a big issue.
I don't even give a shit about the yard. Frankly it's a pain in the ass.
It's about getting away from "the wrong kind"[1] of people.
[1]calm down that's not who I'm talking about.
Are you actually growing your own food though? Or is your yard a grass monoculture that serves more of a vanity project than anything useful?
And maybe you are, which, good on you! But I don't think most Americans are.
