Can you show me one market that ever existed without being regulated by a government?
Any market that could ever exist without direct state regulation would likely be socialist in nature, as with Pierre-Joseph Proudhon's mutualist economy, for instance.
Since you guys won't read it:
The conservative mantra is "let the market decide." But there is no market independent of government, so what they're really saying is, "Stop corporations from defending workers and building a middle class, and let the corporations decide how much to pay for labor and how to trade." This is, at best, destructive to national and international economies, and, at worst, destructive to democracy itself.
Markets are a creation of government, just as corporations exist only by authorization of government. Governments set the rules of the market. And, since our government is of, by, and for We The People, those rules have historically been set to first maximize the public good resulting from people doing business.
If you want to play the game of business, we've said in the US since 1784 (when Tench Coxe got the first tariffs passed "to protect domestic industries") then you have to play in a way that both makes you money AND serves the public interest.
Which requires us to puncture the second balloon of popular belief. The "middle class" is not the natural result of freeing business to do whatever it wants, of "free and open markets," or of "free trade." The "middle class" is not a normal result of "free markets." Those policies will produce a small but powerful wealthy class, a small "middle" mercantilist class, and a huge and terrified worker class which have traditionally been called "serfs."
The middle class is a new invention of liberal democracies, the direct result of governments defining the rules of the game of business. It is, quite simply, an artifact of government regulation of markets and tax laws.
When government sets the rules of the game of business in such a way that working people must receive a living wage, labor has the power to organize into unions just as capital can organize into corporations, and domestic industries are protected from overseas competition, a middle class will emerge. When government gives up these functions, the middle class vanishes and we return to the Dickens-era "normal" form of totally free market conservative economics where the rich get richer while the working poor are kept in a constant state of fear and anxiety so the cost of their labor will always be cheap.
