Libertarians are opposed to states (or governments) creating any "laws" that tell people what they can and cannot do with their own bodies. The only legitimate laws are laws that say a person may not start violence against other people or their legitimate property. All "laws" stopping people from doing nonviolent things should be repealed, according to libertarians. (These "laws" are usually called "victimless crimes" because there is no victim if there is no harm.)
