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)
