Nope, I'm actually pretty cynical about intentions. But the government can detain me, arrest me, tax me, fine me, etc. A corporation can't do any of that.
I'm not sure what you really mean by "monopoly" or what sort of monopoly you think can persist in the absence of government support.
Note, I started my participation in this thread by advocating for minimizing government, which is not the same as eliminating government. So I'm not trying to assert an absolutist position that free markets should have no regulation.
