Unenforceable lawsuits, companies without headquarters, exiles, and the balance between the complexity of the case and resources
Great piece as per usual!
However, want to point out one typical fallacy: "And this monopoly is rather a good thing: having several entities that can use violence on the same territory often leads to wars and insecurity, as in Mexico with the drug cartels waging a merciless war."
Monopolistic states can also lead to merciless war, see North Korea and the countless victims of inter-state war, and witness that states killed 163 million of their own people in the 20th century: https://www.owl232.net/papers/statistics.htm
You can't compare good statism with bad anarchy, you have to compare good statism with good anarchy (i.e. law and order persists, but it's not provided by the state), see e.g. work by David Friedman.
