You're missing the point -- I don't refuse to pay a parking ticket after the court orders me to do so. I don't stand in the checkout line trying to figure out how to run out without paying. I don't threaten people on the sidewalk and take their money when I notice there aren't any police around at the moment. I trust that the vast, vast majority of people act similarly. If they didn't, no amount of law enforcement would be enough.
