Medicare Kills a Program


I dunno, it seems pretty clear to me that the answer is a resounding "Yes!" with the equally-clear caveat that the "customary rights and privileges" may be modified during formalization for three possible reasons:
1. Equal rights: for example, if "customary rights and privileges" explicitly discriminate, for example giving certain rights and privileges to members of one group (males, or members of a certain tribe) and not others (females, or members of a different tribe) then they should probably be modified. The exception might be when there are other rights and privileges which exist to compensate.
2. Compliance with the principles in Epstein's Simple Rules for a Complex World or a similar set of meta-rules.
3. Overall economic efficiency, i.e. reducing transaction costs.
As far as I can tell from reading the report, especially Chapter 6, the examples cited by the authors don't provide any reasons against formalizing "customary" (i.e. local common-law) property rights; they provide reasons against arbitrarily changing those rights by political fiat!
