A completely free market is a market where you'll get collusion, monopolies, price fixing, corruption and a hundred other vices which are considered universally bad. Roaming charges are another good example that a completely free market is not an efficient market. In fact, a completely free market is an anarchy. So not only will you get monopolies and price fixing, you'll also get armed gangs that run around and steal your stuff.
