There's a 'trend', you may have heard of it, known as 'rewilding'. It seemed to come out of something like the same place as the paleo movement; from the idea that we're in an evolutionary mismatch, both with our food and our disconnection from 'nature' (whatever that means) .. and so in one way or another people are reaching for ways to re-establish that connection, or eat and live in ways that are more evolutionarily appropriate. (It's been a 'thing' forever, of course, just by different names.) I'm on the tail end of that hippie, back to the land generation so I've lived that way a bit, and my somewhat older husband, a bit more (he actually lived on a commune in the wilds of British Columbia for a while in the 60's!).
The funny thing is that when people really do put themselves into a position where they are 'living off the land' they discover what humans have known all along; that it's really fucking hard to do. From 'here' it looks noble and romantic, and I suppose we could say it is .. but it's life-threateningly difficult too. Not only that, but when done authentically, it can/will often suck out any and all energy that might have been used for other purposes beyond hardscrabble survival.
