But in real life, any time you have "a free market", by the definition of "no or minimal regulations", you will inevitably end up with a very un-free market, by the definition of "lots of choice for the consumer, healthy competition".

And far, far too many self-proclaimed libertarians think that any regulations that "encumber" the market take it farther away from being "free", when in fact, there are regulations that help and regulations that harm, and you have to be able to actually understand them and use human judgement, rather than thinking One Simple Rule can be applied in every situation without fail to achieve perfection.
