No they are the very definition of free-market capitalism. They are property, and property rights are the entire basis of capitalism. In particular, private ownership over the means of production (which is the definition of capitalism) requires the government grant monopolies to these owners.

Every property right is a government-protected monopoly; without these government monopolies what you have is an end to private property which may be desirable but is certainly not free-market capitalism, it is communism.
