Free markets don't exist. Laws are there to constrain the real operation of a free market, aka 'law of the jungle'.
My experts disagree with your experts:
"The free market, in fact, is precisely the diametric opposite of the "jungle" society. The jungle is characterized by the war of all against all. One man gains only at the expense of another, by seizure of the latter's property. With all on a subsistence level, there is a true struggle for survival, with the stronger force crushing the weaker. In the free market, on the other hand, one man gains only through serving another…. It is precisely through the peaceful co-operation of the market that all men gain through the development of the division of labor and capital investment. To apply the principle of the "survival of the fittest" to both the jungle and the market is to ignore the basic question:
Fitness for what? The "fit" in the jungle are those most adept at the exercise of brute force. The "fit" on the market are those most adept in the service of society. The jungle is a brutish place where some seize from others and all live at the starvation level; the market is a peaceful and productive place where all serve themselves
and others at the same time and live at infinitely higher levels of consumption.
The free market, therefore, transmutes the jungle's destructive competition for meager subsistence into a peaceful
co-operative competition in the service of one's self
and others. In the jungle, some gain only at the expense of others. On the market, everyone gains. It is the market — the contractual society — that wrests order out of chaos, that subdues nature and
eradicates the jungle, that permits the "weak" to live productively … in a regal style compared to the life of the "strong" in the jungle. Furthermore, the market, by raising living standards, permits man the leisure to cultivate the very qualities of civilization that distinguish him from the brutes."-- Murray Rothbard
