"Free Market" is a big hairy term. But, the definition of free market that includes (or expects) all the emergent benefits attributed to free market is limited to a certain realm. Markets with barriers to entry (emergent or regulated, high fixed/marginal costs, any structure that lends to oligopoly, financialization, and bunch of other market characteristics (including interventionist policy) result in markets that are not free in that sense. There is no creative destruction, highly competitive dyanamics and such.
The financial markets have never (and IMO will never) resemble the market for toiletries or music festivals. Neither will many other markets: transport infrastructure, for example, for different reasons.
The free market is an abstract concept, a model. It explains some markets better than others.
