The lure of modern society is difficult to resist: most kids would rather live in the suburbs, play video games, and scroll social media than be sequestered on a remote farm with sparse accommodations.
A close approximation may be the Amish or Mennonites. It's a difficult life, and not prone to explosive growth.
do you mean like half of the worldwide population [0]? or anything on top of that like remote villages anywhere in the world that aren't liberal like hippies but are very much tied to pastoral ways of living? heck if back in 1600 we didn't killed dozens of millions of people maybe this type of communities would be much more widespread
I don't think "pastoral ways of living" are a genuinely held cultural preference for a lot of that population. I'd hazard a guess that quite a few of them want electricity, reliable clean water from a tap, and paved roads.
