It's not free from interference either. It requires enforcing antitrust, for example, which the US seems to have forgotten. Literally what you quoted:
> the term free market refers to a market free from all forms of economic privilege, monopolies and artificial scarcities.
yep, to keep them "free" you have to "interefere" with them
as an aide, the overloading of the term free is really annoying because it muddles things so much...
