I concede you're right. It's not a complete monopoly. My state would allow a citizen's arrest for felony theft, for instance. Generally killing someone over property is illegal, absent some unique circumstances (like breaking into an occupied structure). I'm not aware of any state that allows you to use violence to collect on a contract, however. IF you see taxes as satisfaction of the social contract or whatever. It's hard for me to argue failure to pay taxes as theft; I'd call it more of failure to pay for an involuntary contract. IMO it would be much more appropriately be classified as a civil offense than a criminal one.
