Yeah, young whites are already getting out of cities and forming their own communities. Gentrification is too expensive for them, especially if they want to have kids.
Some of them are starting or trying to start intentional communities, and coming up with all sorts of complicated schemes to try to ensure they live with like-minded people.
Personally, I think a lot of them are naive and highly unlikely to succeed, but I sympathize.
The real key to successful communities is not the communes the idealistic ones tend to envision, but rather old fashioned fraternally organized, faith-based communities, AKA patriarchy.
