For what it's worth, many (most?) countries have most of their people living in places that are not sprawling suburbs. It's worst in the "Anglosphere" countries (US/Canada/Australia) within the last 50-70 years, but it's absolutely not a fantasy land. It's the way things were everywhere before 1940, and most places still are today.
I say that because it is fixable, if we let ourselves fix it...
Your point stands though, even in a fairly antisocial layout of a suburb, you can still usually make friends with a decent number of people nearby.
