Interestingly, one of my ex-girlfriends from my 20s had a dad that did this. He was an engineer and quit to become a farmer, building his own generators and living off the grid powering his operation with waste vegetable oil he obtained for free from the same restaurants he sold artisan vegetables to. He lived in a different state and I only met him once, but it actually did seem like a pretty great life and he was clearly happy with it.

The problem to me when I see this kind of life suggested as something people should try to do is that it isn't universalizable. There are only so many restaurants in any given city that need artisan vegetables. There is only so much land near such cities that can grow it. Even if all people who try are equally able, very few would succeed in doing this.

My grandfather was a farmer. "Out in the fields" or in the workshed practically all day everyday. But he also loved to hunt, had a rental gig on the farm for poor people that wanted to live in shacks "down by the river" (they built the sheds themselves), and would constantly be pointing out to me all the stuff in the house he had built himself (he could have easily gotten them just as cheap and without any additional labor by mail order -- this was post WWII).

Another words, farmers back in that time would pretend they were busy all day. But actually spent a lot of the time "out in fields" bullshitting hunting, hanging with their friends at the river, or having fun building random shit in the workshop out of leisure rather than necessity. I didn't have the heart to tell the women in my family he probably didn't come home sooner because he didn't want to hear nagging or whining children, because it was blatantly obvious to me what the situation was.
