> Surprising to me that year-round veggies is so hard even with modern methods/greenhouses.

You are correct: it is not so hard with modern methods, but none of the small communities I know of (15-50 people) have invested in a greenhouse of sufficient size. And even the local farms here don't have greenhouses, not that I am aware of. That seems odd to me, perhaps I am missing something because that seems unlikely now that I think about it...

Having seen the transformation of Medford/Ashland to MJ and hemp greenhouses I'd think at least some people would be as fanatical about their vegetables/fruits.
