Minor sex workers and children working in mines is both about children labor and their "free choice" to do it.
You gave a ridiculous example about "what if aliens invade us"?
How is that answering my question?
I was answering the portion concerning capital accumulation, would you like me to answer what I think about the age of consent? What age am I supposed to assume people in some some random drawing are suppose to be?
There is not a definitive Anarcho-Libertarian position on this issue, but it's certainly not the "children are cattle" sort of nonsense you're trying say.
I never asked about capital accumulation, I asked about "free choice" of children.
So, are also minor sexworkers, ok?
If not, what is the difference to "choosing" to work in a mine?
Saying there is no "Anarcho-Libertarian position" just shows, that you are cherry picking. Minor sex workers is something in the real world. A theory about society, that doesn't have a position on it, is just a real bad one. Avoiding delicate questions is weak.
