I am on board with 95% of Anarcho-Capitalism but the only issue I still can't wrap my head around is criminal law. I can imagine privatizing everything except criminal law. Common Law and Church Law make total sense for civil matters and relatively minor infractions but then resorts to the Divine Right of King's to justify the force aspect. That is not to say I would be against privatizing criminal law but outside small homogeneous areas (shared ethnography), I just don't see how a totally private criminal system would work. Having said that the everything except murder is inefficient to solve and is honestly one of the arguments for a new system.

My only issues is say someone kills someone and decides to go to a criminal outpost (such as Ciudad de Estes or favelas in general) and tells a defense company to pound sand? My only other issue is adversarial interoperability. At the moment the state might allow private civil law alternatives but as soon as you try to exact justice you are done. Is there a way to deal with harsh crimes in general? I am just not seeing it but I do hope some ideas work.
