We will probably have to fight something like the French Revolution all over again. And not just once, but many times. Centralization vs decentralization. Instinctively humans organize into families, clans, and tribes. Money, technology and kingship forges disparate people into nations, empires and ultimately global organizations. The King, his clergy, aristocrats and bankers inevitably get the nation/empire/supranational organization into war, debt and onerous taxation. Then the shopkeepers, craftsmen, artists and junior military officers go into rebellion and bring things down to ashes and earth again.
