You get something in return for all the risks you listed.

This is why I said "If you are altruistic perhaps".

I'm not and I gain nothing by helping others after I'm dead.

Now if it was the case that in return for being an organ donor I get paid a good chunk of change or some other benefit then sure.

As things stand being an organ donor to me is similar to crossing roads while deliberately paying less attention.
