I strongly disagree. Free-markets are a result of 4.5 billion years of evolution. To think that they can be "improved upon" is purest folly. It's like saying the human brain can be improved upon. Evolution may improve upon it, but humans a clearly unqualified to do so.
This cannot be true by any means. Evolution did not have a market to evolve against. For 99.999999% of those 4.5 billion years of evolution nothing changed because there was no man to invent the idea of markets. Without a
normal market in the first place, evolution cannot select for a
free market.
So it was only after humans started making markets that evolution could select for more optimal actors. But then the selecting force is still kindof vague. Does being a better free market actor allow you to reproduce more and survive better? Do people that participate in these free markets have more offspring? Because that's what you need for evolution to be able to act in any meanigfull way.
Just out of curioucity, can you name an instance of a free market that was not invented by humans but occured naturally and was initiated by some evolutionary process?
