So I’m an organ donor, but because I spend about 1/3 of the year in a country which blacklists me from being able to donate blood in Canada (it’s a policy designed to reduce the spread of malaria), I haven’t been able contribute to our blood banks here in years. So I donate there. I was a regular donor since I was 17.
I would hope that because I can’t donate blood here that I’d still be able to receive blood should I ever need it in our hypothetical. Obviously, children would unlikely be able to consent to donate blood or organs (etc.) and should have access, if not priority access to transplants (etc.).
To me, it’s more about the philosophical or religious divide between people who say YES to donor status, or choose for any reason that’s not medically warranted to say NO to donor status. It just doesn’t sit well with me, obviously, that someone who chooses to not participate in this program, still would expect to benefit from this program.
I’d also guess that we’d dramatically increase the donor list in the province (or country) by having an opt-in/out program. How many people would change their mind on donor status if they knew they couldn’t get access to a transplant without participating?
Obviously, this remains a hypothetical - I'm not sure how you’d deal with the person who chooses to “opt-in” only after they realize their kidneys are failing...
