by that argument coca cola can certainly hire goons to come get you.

how far do you want to take your strawman?

But they won't, because the government won't let them. Even Coca Cola is not above the law.

But government hired goons (aka the police) are the law. In free countries, their role is limited to things like making sure that you won't be bothered by Coca Cola goons, but in less free countries, they are going to hit you for saying things the government doesn't want you to say.
