Libertarianism

Libertarianism is a political philosophy based on the principles of self-ownership and non-aggression. The self-ownership principle holds that individuals have a right to use and dispose of their own bodies and the fruits of their labor as they see fit. The non-aggression principle holds that individuals are only entitled to use force in defense of life, liberty, and property against force or fraud initiated by others; and that this defense must be proportional to the threat and avoid harming the life, liberty, or property of innocent parties.

Libertarians embrace free markets and personal freedom, including sexual freedom. In principle, libertarians would support allowing sex between adults and children, certainly if it could be proven that children are competent to consent to sex, and possibly even without such proof of competence.
