If the "fair market wage" for ordinary unskilled workers were 30 cents per hour, there would be externalities that would affect everyone negatively. Even you. For example, once it becomes completely impossible to live on legal wages, even those who would much rather be law-abiding would resort to crime. If you give businesses absolute freedom, they will immediately use that freedom to create barriers to entry and prevent competition. There is no such thing as a "free market" without regulation, because abuse of power is gigantically profitable. There are also no property rights without government and courts and police to enforce them. There is also no ability to contract (and be sure the other party lives up to the terms) without government and courts and so on.
