Well add to that that you're assuming that "right" rules that are pareto efficient 1) exist 2) are significantly different from capitalism All non-trivial pareto efficient rulesets I've ever seen involve some form of revenue sharing between both parties. Given what pareto-efficiency is, I think this may be a general property. Obviously somehow both parties need to be bound together for pareto efficiency to happen. Money's one way to do it, and I don't know that many others.
