Easier said than done. I think it's probable that some problems are so difficult to translate into proper market motivations that the cost of the perverse incentives inevitably produced by your attempts will consistently exceed the potential for increased efficiency and miraculous innovation that the market promises.

You are neglecting to examine the counter-factual. The current system is abound with perverse incentives and flaws. As to the difficulty of designing a new system; we have thrown money at a poorly designed system for many years with little success, perhaps a redesign would be worth it.
