This is an odd way of thinking about rule of law. It would be more accurate to say that (ideally) police and laws are their to enforce parameters which “most people” would agree constitute a functional society. Things like “don’t murder people”. You could totally murder people if you wanted to. But it’s best for everyone if you don’t. It has nothing to do with trust or me thinking that everyone around me might murder me. It leaves the trust bit up to the individual and this is evident every time someone gets in a car and drives at 100 kph toward another car while never even considering the potential ramifications of the opposing driver swerving just 2–3 feet.
