It'll be like in the Godfather, the heads of the families that you pay tribute to will meet and arbitrage a deal. (srsly, it's pretty close to this).
Except organized crime needs government in order to be profitable. Think of it like lobbyists who make something illegal for everybody else but the companies they work for. The company no longer has to worry about competition because the government wont allow anybody to start a similar business.
Its virtually the same thing with organized crime. Your reasoning for not dealing drugs or running a casino in your garage isn't because you're concerned that the mafia is going to extort you for a cut or muscle you out of business, its because you're worried about a SWAT team kicking down your door.
Which is why minimal government is the way to go, not complete anarchy.
My 2c.
So they can grow government 8 to 10 years later, raking in windfall tax revenues after the economy has been soaring, and buy more guns so they can show us they're still in charge.
If you look at this from a global scope, we're already living in an anarchist world, we have security firms (the governments) competing over talents. If you don't like it, you can leave. Pledge to a government that suits you. The fee? Taxes.
Actually, that's called panarchy, and its not a good thing. Comparing the global political environment (panarchy) to anarchy is like telling slaves they are free to choose which plantation they want to serve, while pretending there is no such thing as north.
