Well, I don’t do that anyway.
My point is that eventually it feels like it’s gonna be illegal to pick your nose without a fine. Where does it end?
How is this even remotely similar? There is a big difference between a law that punishes behavior that is dangerous to the community and a law that punishes behavior that is not socially dangerous. Your example, for instance, is behavior that has no impact on the community. A law that requires motorists to stop for children getting off school buses, on the other hand, exists to ensure that children don't get run over by a guy in the car who is too impatient to wait ten seconds while a kid walks to his door.
Or maybe you think that is a "bad" law. Do you agree or disagree with a law that requires motorists to stop for children embarking/disembarking school buses? If you agree that a law is warranted, then shouldn't the penalty for a violation of the law be sufficient to deter people from breaking the law?
