Man, I was at PF, and I don't think I saw any of this shit, or met any of these people.
If I recall correctly, you were too busy drunkenly arguing with David Krouse that children should be available for sale ...
For sale as labor, or as in purchasing a newborn from a woman who hasn't the resources/desire to be a mother?
"for pleasure"
I would assume that a guardian would be responsible for the well being of a child to a certain point (I don't know 14?) and would have to stand up for the results once the responsibilities were done. So if one "rented" out a child one was responsible for, the child could receive restitution as a adult. Still sounds fucked up. Any real philosopher dealt with what to do with evil guardians in a libertarian society? This is a tough one for me, I dislike abusive parents and I hate child services as well.
In Cuba Young prostitutes would support their starving families because this was the only legal trade the commies let happen for a while.* I know its not so black and white, but it is sad and I think important to discuss.
