Bringing necessities (water, food, energy) local is worth subsidizing. For those who doubt, just look at current events. Two morons with the right levers can upend countless critical processes.

If you look closely enough, everything is government supported. However farming is explicitly government subsidised everywhere.

That's a hard thing to have introspection in as just about every productive source of food probably has some government support.

Just about everywhere has understood "bread and circuses" and "let them eat cake" to the point of monetarily promoting food production.

One of the big distinctions between feudalism and extreme capitalism in my mind is forgetting this.
