[...]None of these examples invalidates the principles of voluntary agreement and non-violence, or even lex mercatoria for that matter.
You can keep saying I need a state to defend my property, but I am happy without that state doing it. Maybe you aren't, because you keep trying to sell me on the idea of needing it, but I am not buying.
Nah. You're buying, you have always bought, and you will continue to buy in the future. You're living in and by the laws of the state, enjoying its benefits & enduring its hardships. You pay your taxes. You answer the door when the cops knock. You probably have a driver's licence. I doubt you're manning the barricades with your AR or AK. Amirite?
I have a property far away, one I don't use much. I have a friend that has done heroic things but is down on his luck. I say to my friend, "friend go and stay at my place on the beach". Take care of it and see what you can make of it. There were some squatters. They were not good custodians and were persuaded to leave without any authoritarianism or threat. If instead they had been good custodians, they easily could have stayed and shared.
In other words, your down-on-his-luck buddy reasoned with the squatters, they've seen the error of their ways & chose to leave? That choice didn't have anything to do with your buddy's shoulder holster or the likelihood that statist thugs (cops) will appear, similarly armed, if they didn't comply?
I have never called the police for anything, and never asked for anything from them. I supply my own security and am happy to remain doing so.
By security, i assume you mean "GTFO or find out how strongly i feel about non-violence," right?
The way you sound is that there are all these monsters roaming about looking to destroy and loot and steal so we need to run to our government constantly to protect stuff, but in the real world, if I have a problem with someone, I deal with it directly myself.
The lack of roaming monsters could be largely attributed to government thugs. If by "the real world" you mean your fantasy land without governments, then please regale me with stories about prehistory, or at least Somalia.
Personal security is one of the costs of personal property. If you can't afford that part of the cost, then you cant afford to own it in the first place and are better off putting the resources to some charitable purpose. Because property rights do corrode. Time is our ultimate judge, and you can't take it with you.
What he can & can't afford is irrelevant. You are an American. You have never lived in a stateless society. Your imagined fairyland has as much in common with reality as Equestria. Grow up.
