The edges of everything are blurry. Including private property. We can all agree that if you worked for a wage at an honest company producing goods people need that your money is yours and taxing it would be theft.

But what about the land that you claim that wasn't owned? Surely someone had to claim it at some point if not you.

The uncomfortable truth for all anarchists is that there is no abolishing aggression. There is, at best, minimization of it. At the end of the day, some conflicting claims really are just best settled with violence. Preferably the swifter the better, and with the least collateral damage and impact to productive endeavors.

To quote Tony Soprano, 'when the guys are going to mattresses, they're not earning!'

The real problem with the state isn't that it uses violence. It's that it abstracts violence away from the situations which call for it, and through the repression, magnify it and increase the damage it does.

Left to our own devices, most of us will avoid unnecessary violence because if any alternative path exists that can provide an amenable outcome, we'll take it. The state thrives on our willingness to outsource the violence, and by the time the chickens come home to roost, we're left unable to get out from under its boot.

Tl;Dr celebrate violence. The fact that you're here is because your ancestors mastered it against their opponents.
