Defining a market is itself an external influence. There is no object that is intrinsically a market: all markets are made to exist by human action. Sure, it would be nice that those external factors that define a market don't change too much too quickly, and that those factors are clearly and openly accounted for, but all markets are unfree if this is your definition. It is an ideal that cannot be realized because it is incoherent. I think your example of a non-free market would better be called unfair. Of course, everyone has a different definition of fairness, but it's a useful term for discussion to coalesce around.
