> No, it is an economics term describing a type of market.
It's both; it's an economics term describing an idealized abstraction which does not (and arguably cannot) exist in the real world, and a propaganda term applied to real markets which, without exception, diverge radically from the idealized abstraction.
"Regulation" is another term that's been abused to the point of meaninglessness, for that matter. It's largely just a synonym for "thing I don't like" now.
[EDIT] it's a bit like "right", which is mostly a term of propaganda, too. Declaring something's a right is propaganda. Declaring something's definitely not a right is propaganda. It may be useful in that role, but it's not especially useful in deciding policy. And yes I'm familiar with from-first-principles attempts to distinguish "natural" rights from everything else. I've even read the Second Treatise. It's all just-so stories, not some law of reality.
Free market without any regulations will work as long as people are simply decent. But we are human, poor man wanna be rich, rich man wanna be king etc. So some regulations are needed. But not so many of the lobbied ones, as the corporate interests should not be the primary concern of the government. IMHO etc.
