Milton Friedman was a free market philosopher known for his work in advocating for limited government intervention, free trade, and individual choice in the economy.
John Locke, Adam Smith...and others
I attempted to improve the question to read as this: Was Karl Marx a free market philosopher? Some how I could not do it. The answer however is that Marx was not a free market philosopher. He was an economist, political analyst and philosopher that believed the capitalist economic system oppressed the working class. He believed that any remnants of free markets would fall into the hands of capitalists who would destroy itself by frequent depressions. I say this to make it clear that "free markets" could evolve into a socialist economy. Marx believed that only a violent revolution could change the economy.
Arguably, Adam Smith is a philosopher and economist who wrote the book Wealth of Nations that expounds on the earlier forms of Capitalism. John Stuart Mill is another philosopher who supported the free-market. W.V. Quine is not a philosopher of capitalism but he personally favored fiscal conservatism.
One example of a free market philosopher is Adam Smith, known for his work "The Wealth of Nations." Smith advocated for a laissez-faire economic system where individuals pursue their own self-interest, leading to overall societal benefit through the invisible hand of the market.
In a free market, there is profit to be made by making the free market not a free market. Therefore, a completely free market destroys itself.
Voltaire
