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.

What repercushions exist for violating property rights as a group, or should exist, and what parties and actions account for that?
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.
