If you try to write down every case of being a jerk instead of just having a society-wide agreement "don't be an utter jerk", you wind up with lots of fine print, rich lawyers, and at least as many people still being jerks.

Consider the complexity of a vending machine vs. a can where people can leave their payments... Any society probably has places where you need the former, and places where you can get away with the latter, but I prefer those societies where most of the places in between are on the can end of the spectrum.
