Smoking, drinking, gambling, pornography, prostitution etc.―leading human beings astray, these ought to be banned essentially. In that case, however, freedom of each individual will be limited. Therefore, we should allow the government to impose heavy taxes on these actions and to take a lot of money from fools by force. Because slaves of passions forgetting self-control impose too heavy a burden to the state, we can be more convinced that this measure is rational.
