A lot of logical fallacies going on here, and logical level-crossing.
Genetics is a method of optimizing resource use to achieve goals, and brains are simply an faster way of doing so than genetics alone.
The human mind is also a seeker of local optima, shortest path to achieve certain goals, which often involve coercion.
The free-market is an organic result of human minds seeking optima, and not a "creation" in the sense that a car, gun, or space shuttle are creations.
The free-market, also, by it's very nature, does not involve coercion.
The free-market has proven, time and time again, to be the optimal wealth distribution method, and as it is a natural result of the human desire to be more wealthy, as opposed to some clumsy system dreamed up by some ideologue (like Zeitgeist, communism, etc.), will always perform better, as it is the result of 4.5 billion years of evolution. (Evolution = seeking optima)
I think your distinction between "seeking optima" and "creating useful things" is false/blurry and unecessary.
By your definition, free-markets are rarer than things people say are free markets, or a lot of markets are occasionally un-free.
I mean a person held at gunpoint is free to choose some things but there is an element of coercion.
I generally find it foolish to believe that either a human creation or organic patterns of human behaviour are universally and permanently adaptive, and then there is the possibility that other traits may be more adaptive, more optimal, and yet to come about. There's more than one way to shape an arrowhead.
Note that just because one trait dies out or does not dominate does not mean it is more adaptive. It took catastrophes to unseat the dinosaurs despite Mammalian's advantages. Surely some mammals were extirpated by more established reptiles.
Human resourcing today and the phenomena of free markets really are amazing despite their problems, but I'm sure most people agree that it could be improved upon, or at least better implemented. Keeping politics out of markets is a false dilemma if anyone is thinking that. Every action is in some way political, at least while humans are humans.
