That is why we must have government. Angels do not govern men. That is why we must have constitutions. Guns are dangerous in the hands of anyone. But each of us is responsible for his own life.
Guns are dangerous in the hands of men, even if the men happen to work in the government.
It is not any different. What is at stake, then, is not efficiency. It is not prosperity. What is at stake is not even only freedom. It is also morality.
