Fine, self-ownership is a axiom, so what? If I can’t do what I want with myself (like being employed) then why bother to call it self-“ownership”? You need to break it down, showing me how the self-ownership axiom some how makes it morally impossible, because in your above post you seem to ignore a very basic fact, that if I own myself which I do, no other person can tell me I am morally wrong to engage in employment. (Reason being because I own myself and am free to do whatever I want with myself.) What your doing is basically saying no matter what I want, I can’t work for someone, morally speaking, yet I still somehow “own” myself. That’s like a parent that tells their child, “You’re your own person”, then tells them they can’t do X, because they don’t approve, but offer a fancy excuse as to why.
(FYI: My post never denied self-ownership. I gave you a choice, either self-ownership is indeed a axiom, in which case I can do what I want, including “renting” myself out, or I don’t actually “own” myself. It was meant to show how you can’t hold self-ownership as a axiom and at the same time say a person can’t do something with his body or his labor, and how it is contradictory to make both claims at the same time.)
