If not them, I see potential in local mutual aid orgs (Here we have an anarchist militia, the Colorado Mutual Aid and Defense) and whatever party/movement steps up when the economy goes to shit. With something like log colonies, that's a foolproof method of recycling waste (I just got like two dozen logs for free from a guy cutting down an invasive hardwood species, municipalities and homeowners trim theirs all season) with 1-3lbs of mushrooms per log per year growing anywhere there is shade and a hose. I keep looking at the space I'm putting my new batch of logs, a barren rock path between my garden and garage, and seeing it as a small contribution to a project which is still larger than I'd be able to contribute in vegetables. A few large straw oyster logs cost all of $5~ and make 6-12lbs of high quality protein that has positive effects on poverty-linked illnesses like diabetes and cardiovascular/immunological/neurological dysfunction. When meat is unaffordable, that's a very powerful niche providing the luxury part of a meal and the bread book to go with the bread.
