It's not though. The vast majority of people can't just uproot their lives and move to some rural area. That lifestyle isn't universally accessible. You are overlooking the financial, social, and logistical barriers many people face. Are you Libertarian?
I grew up in SoCal and almost all my family members, neighbors, and friends uprooted and moved to the South. It's just cheaper. And in many ways forces you to be self sufficient. Nobody's asking you to do it, but don't try to limit folks options if they want to. You don't see me telling people "don't go here, don't do this". I'm a possibilities kinda person and I don't mesh well with folks who don't believe in them. So, have a good day!
