What is wrong with that? Allowing them to donate organs gives them more choices. Who owns a person's body?
And donating the organ helps people who needs organs. The person who donates and the person who receives do this voluntarily if they feel they benefit.
I think it's deplorable that people are dying from lack of organ donations while there are people with healthy organs who are poor. Legalizing organ donation would help both groups.
How many would out of desperation i.e. healthcare costs for relatives sell an organ?
