Yes, but once a monopoly happens, that market is no longer free, competition becoming impossible without regulation. A monopoly can also supply virtually unlimited resources for expanding in other markets without breaking any antitrust laws.
The only thing that can break monopolies naturally is technologicall progress, because only new technologies can make older monopolies obsolete. But then again, relying on a constant stream of innovation to keep our economy from collapsing seems like a losing battle. And also, lately technology is all about making rich people richer and poor people poorer. So much for hope.
