I enjoyed that parody, but it kind of misses the most parody-able bit of all of the libertarian polycentric law research project; the general assumption that these systems are superior for not involving a state (not explicit here, but certainly true of David Friedman and Van Notten in general)
"Examples throughout history prove the state is not only inherently evil, but also unnecessary to provide satisfactory legal resolutions. For example, in U̵t̵o̵p̵i̵a̵ Somaliland satisfactory resolutions are ensured by independent judges free to make up their own legal principles, murder is deterred by having suspected murderers' family members executed (if they're too poor to pay the fine), clans claim the right to extract larger fines for the same offence if committed by outsiders and judgements may either be accepted or enforced by vendetta"
