For example, a repo man can be one layer of rights enforcement. How do property owners use private resources to minimize escalation while asserting their rights when multiple people get involved.
For context, this is what can happen in some communities if you try to repossess something: https://gvid.tv/v/zJVKda
What repercushions exist for violating property rights as a group, or should exist, and what parties and actions account for that?
I will also submit my own solution taking from my prefered form of anarcho-capitalism that does have a centralized civil court of last resort. It is intended to be a general solution but I think we can see how it might also function here, which is based on Somoli system of Xeer.
To me, the main problem with law is criminal law. There is no need for it. If there is a victim a civil case can be brought. If there is no victim it doesn't need to be a public matter. To the extent that victims need justice, actual justice is better rendered by the victim recieving compensation rather than society recieving paying in the form of paying for someone to waste time.
For this reason I suggest not getting rid of the civil system. Many advocate a decentalized civil system, but I suggest a civil system of last resort is usefull for when an agreed arbitrartor can't be found or continued violation of arbitrated orders are ignored.
But would it be voluntary? Yes. Absolutely. Attendence to a civil hearing, or abiding by its findings are completely voluntary. But then why recognize its authority? Because you want there to be a civil court of last resort. If you don't abide by its orders it will do nothing. Precisely nothing. But it will continue doing nothing. If you have a civil issue the court does not recognize you and you lack a civil arbitrator of last resort. That would mean that anyone can do anything to you and there is no system in place to protect you.
Under the Xeer system, punitive damages are set at 3x the recompensitory damages. So if you steel 0.0002btc from me and it can be demonstrated in a court you would then owe me 0.0008btc back. This incentivizes people who will eventually be shown to be in the wrong to settle early, either by making right before its brought to any third party, or by being agreable to adhere to other preliminary arbitrators.
In this case you could make a claim that the crowd is responsible for damages, and use video to identify them. You then could hire someone to hang around the community to identify them and serve them. If the whole community fails to comply their whole community could become unrecognized by the court which would be a bad situation for a neighborhood to be in.
What's great is this system doesn't even require private cops. Cops are for putting people in jail. Are you going to run an anarchist jail? Jails are for criminal law, which doesn't need to exist. Being unrecognized by any civil system is a fait worse than jail anyway and so enforcability of individual rights can be achieved without cops.
It would be fantasy for anyone to suggest that would even be possible. Freely associating groups are always going to have some system of arbitration regardless of the existence or lack of common law. Though I cringe at the mention of a Somali tradition when anti-anarchists love using Somalia as a prime example of anarchy in reality.
