When using that, it's not talking about self defense. The government has a monopoly on the use of violence in the sense that if you owe them money or some other obligation, they may go through paperwork, collections, all the normal resources. At some point, though, they will send people with guns and physically collect you. Don't pay the IRS for long enough and the government will use violence against you, generally in the form of locking you up against your will.
