Why should selling organs be legal?

It should be made legal (for the owner of the organs) because the hospitals and surgeons are making millions from organ transplants...

So a person should be able to decide if they wish to just donate their organs or to sell their organs and have the money distributed to their family members or who ever they wish...

A person should also have the option of selling their organs while alive (IE) selling 1 kidney,part of the liver,1 lung,bone marrow,Blood,ect.

The US is always short on organ donors,offering cash payments would greatly increase the number of available organs..
