@Robin My idea of ideal world is just an extension of Adam Smith idea to area not normally governed by free market.
Basically the market is the ideal form of government. If you can’t get free market, get something close.
Look at patent laws for example. Not exactly free market. But there is a check and balance there. How do government reward inventor? By the worth of the invention. How? Well, give the inventor a right not to allow others to use his invention for 25 years and see how much money people are willing to bribe that investor. Not perfect, but not too bad for a start.
