Legal tender and taxes

In a truly free-market economy, money would not be monopolized by legal tender laws or by a central bank, in order to receive taxes from the transactions or to be able to issue loans.^{[citation needed]} Minarchists (advocates of minimal government) contend that the so called "coercion" of taxes is essential for the market's survival, and a market free from taxes may lead to no market at all. By definition, there is no market without private property, and private property can only exist while there is an entity that defines and defends it. Traditionally, the State defends private property and defines it by issuing ownership titles, and also nominates the central authority to print or mint currency. "Free-market anarchists" disagree with the above assessment – they maintain that private property and free markets can be protected by voluntarily-funded services under the concept of individualist anarchism and anarcho-capitalism.^[15][16] A free market could be defined alternatively as a tax-free market, independent of any central authority, which uses as medium of exchange such as money, even in the absence of the State. It is disputed, however, whether this hypothetical stateless market could function.[...]http://en.wikipedia.org/wiki/Free_market
