What would New York even do? People here don't believe in firearms, let alone violence. In reality the city would starve within a couple weeks due to siege/blockades if it really united and tried to revolt.
Kropotkin's Bread Book is about exactly that! He claims any revolution will be as successful as its ability to feed everyone, and tries to outline a path to it.
I don't know what that means. Guns are highly correlated with leathality and people believe in them completely. Generally, a population may not want to have possession of guns. That quickly changes for a large percentage in survival mode. Effectively, many criminals are perpetually in survival mode.
