Yea, but it's just like any real free market in that there's no guarantee other's won't find a competitive advantage over you, survival of the fittest.  Whether that advantage is building a factory with Chinese peasant slave labor, or operating an unlicensed nuclear reactor on the bottom of the ocean floor.  As long as you can perform the hash function on a CPU that existed before Bitcoin was even releaesd, the fact remains that it is a permissionless ledger.
