The question is bascially just that simple. This was prompted by my viewing another post on child pornography in a libertarian society, and whether the making and sale of it should be permited. One poster basically said that parents own their children until those children reach the age of consent (thus implying that coercively forcing children to participate in sexual acts for the production of child porn, so long as it’s the parents that do the coercing or otherwise allow it to happen, is OK). However, how is the age of consent to be determined? Since any libertarian that supports any sort of state apparatus can easily answer this question by saying that the state can deterimine the age of consent by way of a statute, this question is mainly directed to Anarcho-Capitalists, since possible solutions to this ethico-legal dilemma interest me. However, anyone who wants to put in their two cents to this is free to do so.
Also, as a supplementary question, should there be different ages of consent for different acts, or should there just be one in which you attain total self-ownership and are allowed to do all things for which the idea of an age of consent may possibly be applicable? For example, should you legally be allowed to have sex and drive at, say, 16, but not be allowed drink and smoke untill age 18? What about individual differences in intelligence and maturity levels among children? The examples in the question, by the way, are just that - examples. They do not necessarily reflect my own views on this question.
I’ll be sure to provide my own view on this later on as the discussion progresses.
