Your fear that law-abiding society would begin to unravel as soon as some citizens broke some laws with impunity, would not be realised. Give 'em an inch and they'll take a mile. Look at the inner-city riots. As soon as the officers of law enforcement retreat, total anarchy fills the power vacuum. Come off it, Tom, people don't riot just because they can get away with it.
Riots occur in unusual conditions.
Most people, most of the time, obey most of the laws. If the whole population resolved to disregard the law, no police force could stop them. The courts say they'll jail poll tax refusers. Yet, if half of Oxford refused to pay it, they'd physically swamp the prisons. Government by coercion simply cannot be done.
