There is only one natural law, and that is reciprocity. That law is empirically evolving at all times in that branch of law we call tort. That tort law evolves by incremental suppression of parasitism by new discoveries of ir-reciprocity that violate the one law of reciprocity.
The principle problem in tort history is the failure to define property as property-in-toto, and this problem has been caused by the Ruler’s interest in preventing defectors as well as defeaters, while at the same time collecting fees for doing so.
Like regulating an economy via money supply, we have a very hard time finding a measurement that provides us with decidability that produces no even worse externalities.
The answer in both cases is markets, rule of law, and universal standing in matters of the commons, such that the governor is not necessary as other than a judge of last resort.
The west invented rule without government for the same reason we invented law without discretion: the consequence of a voluntary militia of equal sovereigns is the only decidability that is possible is tort (reciprocity).
