Why do we not allow people to sell organs?
The top-level answer is because people do not own them. As far as I remember, in the US people do NOT have property rights in their organs and tissues (yes, there were court cases).
Digging deeper, allowing people to own their organs and tissues would make life more complicated and expensive for the medical establishment and it doesn't like that.
That makes a lot of sense. The healthcare industry would be down several thousand dollars per kidney transplant if people sold instead of donating.
The ownership thing, ugh, why do we allow people to donate then.
This thread is for asking any questions that might seem obvious, tangential, silly or what-have-you. Don't be shy, everyone has holes in their knowledge, though the fewer and the smaller we can make them, the better.
Please be respectful of other people's admitting ignorance and don't mock them for it, as they're doing a noble thing.
To any future monthly posters of SQ threads, please remember to add the "stupid_questions" tag.
