Firstly, 'The free market' can never be 'a moral system'. The first term refers to a system of trading, where goods and services are interchanged and relative monetary values are established. The second refers to sets of principles, reasons and motives for doing certain things. The first is at most a subset of the second, but that is only the case if you amend it with a philosophy that equates monetary value to moral value.
Secondly, your view of free markets is naive. Lack of transparency and the problem of monopolies are only a few of the many problems that completely free markets suffer from. We have an FTC, because markets need to be regulated. Leaving them completely free leads to morally unacceptable results.
