@UncleIroh In regards to the thought experiment, nobody complains about tyrants when the tyrant is enforcing laws and values you agree with. Pinochet was a dictator who hated communism and employed free market capitalists to reform the Chilean economy and create "the Chilean Miracle".
So while a "decentralized North Korea" sounds like hell, it could end up being like Singapore. It all depends on who is in power, not the style of government.
