Facts:

We do not even own our own bodies, we do not let people sell their hearts. However, we do let them sell their blood and we let them sell their hair. I wonder if we would let them sell some of those things after death. If people really owned their bodies in the same way that they own property, we would presumably allow people to sell all of their body parts. Do we let people destroy their bodies? For centuries there were laws against self-mutilation and against suicide, now while we do allow organ donations upon death, would we allow a person to give his or her heart, while alive? When Eisenhower was President and had a heart attack, a few people came along and said that they wanted to give him their hearts. The technology was not developed enough for this to become a reality and most members of the public thought that these people were crazy. In any event, I do not think we would let living people give their hearts away merely because they were tired of living.
