Yeah I'm not suggesting that we all need our own subsistence plot or anything although I see nothing wrong with that lifestyle. I am not necessarily advocating for any specific size of farm, but I think government subsidies allow farms to grow beyond what is reasonable. I think the large scale shipment of food around the world results in a lot of waste, and I really think that waste is underappreciated when we operate at large scale because it is abstracted away.
I think some foods can only be grown in certain areas, so I'm not suggesting no food should be traded outside of a regional zone or anything, but I think we should evaluate more carefully which things might be more decentralized and take steps to reduce bureaucratic processes that create weak points in food distribution.
