I think it would work quite well if we slowly reduced the population to less than half a billion. Think of the vast concentration of humanity living packed together in cities. Where would they go? Where would they find good land? It simply won't scale for 8 billion people. Without industrial farming we could not even feed 4 billion right now. We have overshot the Earth's natural carrying capacity by that much. We don't even adequately feed 8 billion now.

I'm reminded of the American Indians. They lived a extremely sustainable lifestyle and all without any ownership of the land. But there were only 60 million living in the US when the Europeans invaded. Try that with 332 million pampered Americans.

I admire your lifestyle and commitment I just don't see it scaling up anywhere near 8 billion. If people claim industrial farm land for their property and reduce industrial food production people will starve, but we will come to that anyway. We have yet to see the ripple effects from the "bread basket" that was Ukraine.
