This situation kinda reminds me of John Locke talking about slavery. He says that for some rights to be truly inalienable, that people themselves should not have the ability to willingly surrender them, such as by willingly selling themselves into slavery. Now, yes, John Locke owned stock in a slave trading company, so he’s a hypocrite in that regard, but I digress. I feel like this is one of those things where people shouldn’t be allowed to physically sell parts of their body for consumption, as “not being eaten by other people” is one of those inalienable rights we should have as a society.
