The success of a measure of prohibitionism has been criticized as often depending too much upon effective enforcement of the relevant legislation. Some people have argued this is because the majority of the targets of prohibitionism are in the category of victimless crime, where they claim the harm that comes from the crime is non-existent, questionable, or only to the person who performs the act and even then the magnitude of the harm being relatively small. Under this interpretation enforcement becomes a conflict between violation of statue and violation of free will. Since the acts prohibited often are enjoyable, enforcement is often the most harmful choice to the individual. This sometimes results in laws which rarely are enforced by anybody who does not have a financial or personal motivation to do so.
