The computational complexity seems to depend on the desire to solve all the problems at once. But how about solving just the warped incentive structures of capitalism? Simulate perfectly rational economic actors that are only concerned with the next upstream and downstream hops in the market, have them take into account the "taxes" and "credits" of externalities without any of the pesky politics, and distribute in-simulation "purchasing power" to end consumers in whatever way you deem fit. You could even distribute this end-user power to actual consumers, in order to allow them the freedom to input their desires into the system. Basically, remove the capitalists from the capitalist system; or, just use the computational model of capitalism without actually giving power to the computational nodes.
