In a perfect world, I think everyone has access to their own stem cells as opposed to sifting thru donor pool.
Donating is definitely awesome, but there's a lot of research surrounding how cord blood transplantation from related donors (or yourself) increases your chance of survival from a stem cell transplant vs. using an unrelated donor. https://www.nejm.org/doi/full/10.1056/nejm199708073370602 - there's a chance of rejection. This woman found a partial match, but she was lucky. I assume she's only 2 races or a common mix i.e. half white, half something else
Finding a match later on can also be much more expensive than keeping your own!
