Arbitrary laws have to be enforced with disproportionate punishments. Reasonable laws are based in common sense and exist for everyone’s benefit. Reasonable laws are enforced with proportionate punishments. Why? Because people follow reasonable laws for their own benefit. A man doesn’t drive 100 miles an hour on the interstate for two reasons: first, because he will get a ticket and second, because it is dangerous to drive that fast. The fact it is dangerous means he follows the law for his own good.
Arbitrary laws are attended by disproportionate punishments, though, because no one feels their life is naturally and obviously better by following those laws. The punishment for breaking arbitrary laws must be awesome, baffling, for people have no good reason to keep them otherwise.
