Communism worked great, up to maybe four dozen people. Libertarianism was a bit better and could handle thousands before it started to fall apart. Capitalism worked best on scale, but it too began to implode once you moved close to the billion mark or so and began to factor in multiple local governments. Socialism always sucked and tended to work like a glacier moving uphill, but it worked at pretty much every scale in the same way. It was reliable, even if you could only rely on it to piss you off and barely get anything done.
