Food prices go up, and it will be economically feasible for all the right wing hippies out there to maximize their home production, and put their kids to work.
The trading aspect of local agriculture is the best part. One of my trading partners took my garlic stems after I harvested garlic. He’s going to make garlic juice for seasoning from the woody but still green stems. It’s used to flavor meat. He also dehydrates garlic scapes and grinds them into a seasoning powder.
I could produce mountains of garlic if it was worth it to do so. They are self seeding like crazy at this point, and if I save the seeds and grow them in pots indoors, they’ll grow very well and they tolerate crowding in a pot and transplanting very nicely. Or if I merely transplant the volunteers, fertilize them a bit, and make sure to cut the scapes in time (h/t to Hardscrabble Farmer), I can get LOTS of garlic.
The small farmer as a cultural force and a massively distributed political influence could come back with a vengeance. People spending time weeding in the hot sun and watching for rain and planning for next years crops are naturally right wing. People who breed animals understand eugenics implicitly.
Sometimes things can turn our way, without our intervention. It’s not a deus ex machina as it is the working out of the internal contradictions of liberalism. Liberalism is not materially, energetically, or economically sustainable, and it is HATED by a lot of good and decent people who can’t wait to kill liberalism, bury liberalism, and piss on its grave.
