No, unless the slaves voluntarily sold themselves to slavedom,
I'm sure that you have to realize on an intellectual level that this statement is impossible. Even the S&M sex slaves aren't really slaves, they're just play-acting. You cannot 'sell yourself' beyond a limited term and under very limited conditions, thus nothing like chattel slavery at all. Even those same S&M sex slaves have that 'safe word' that makes it all stop.
Yes I know, By selling yourself as a slave you give up the freedom that you as a libertarian claim cannot be given up, and so on, hence the back door, which actually just makes it a long term employment.
No, I think you misunderstand the point. The core right of mankind is the right to life. If I own myself, which I obviously do, I own my life. If I truly own anything, that means I have the right to destroy that thing. I have the right to destroy myself, and I can actually sell the right to destroy myself to another. However, if I were to sell myself to a human-hunter for sport, and he fails to follow through, he's also 'quit' his claim and, by reason of my own continuing to exist, have immediately homesteading my corporeal body once again. It's not the selling of self in the moment that's impossible, it's the ongoing arrangement that is impossible, because I can change my mind at any time. And if I can change my mind and walk off the chain gang, then it's not really slavery, is it?
Selling yourself to slavery and selling your own organs is usually some of the most debated questions in the libertarian community.
Not in my experience. Both issues seem pretty well settled. The first isn't prohibited in any way, it's just impossible to sustain; and the second is obvious. If I own myself, which I obviously do, and I have the right to destroy myself, which I do, then I have a right to part myself out. The tricky part is proving after the fact that it was an agreement I freely entered into without coercion. If I'm only selling one kidney for a very large sum of money, and am still alive after the fact to assert that my kidney wasn't stolen from me, then I shoudl be able to sell that kidney; and I should be able to buy one in like manner. However, selling
all my parts is tricker, since it becomes less obvious that I actually gained anything. ; but I can think of a scenerio or two where even that would make sense. Say, for example, I had an inoperable brain tumor, but my heart was in excellent shape. My own doctors gave me six months to live. Then some really rich guy comes and offers to pay my next of kin an ungodly sum of money for my heart, because he has a teenaged son who needs a heart transplant in the next 3 months and I'm a match. IF I coudl verify that my own bills woudl be paid, and a fund set up for my kids to go to college, such a trade woudl be rational as long as I truly believed (and had not been decieved) that my own life was short.
