I think this is the ultimate extension of anarchism. Under anarcho-Keynesianism, everyone would be totally bent on “growth” and there would be no one to stop us! No commies or Marxists, no “free market fundamentalists” like Ayn Rand and Mises, no namby pamby pacifists or “Old Economics.” Finally a system for everyone! The best of anarchism, centrally-planned markets, and yes… John Maynard Keynes!
In this commune, we’ll have meetings every morning to discuss Paul Krugman articles in the New York Times, we’ll be fully employed at all times on public works projects, property rights will be sorta half-way as we’ll need to break windows and pitch in huge bucks to fight other communes now and again (but always rebuilding them of course like English gentlemen; other Keynes communes will just have insurance built-in so it won’t matter). But it won’t be one of those Jonestown type deals like Anarcho-syndicalism or anarcho-communism.
Just think: a whole economy built on blowing crap up, big statues and monuments of stuff, “green” makework and featherbed jobs, ever-widening freeways and interstates, and no gridlocked Washington DC to stand in our way!
Actually, Bryan Caplan used that one first. Therefore, according the the natural law of IP, you owe him an aribitrarily large amount of money for trademark infringement.
