Impulse control and deferred gratification should be taught to children as a matter of course. Without that you have uncivilized barbarians and no society to speak of, anyway.
Respect for the law is easy. Make sure every man, woman, and child has a gun and knows how to use it. Make as few laws as possible so that everyone can know the whole of the law.
Sixgun justice is no justice at all. Human beings established the state because they did not wish to live under feud, vendetta, warlord anarchy, or the bullying of the mobbed up. Adults established the state because there is no worse tyranny than that of a teenage boy with a gun in a lawless world.
With thinking like yours, no wonder libertarianism is and will always be a common sense-deficient fringe.
