I live in Austria where every person is an organ donor and you have to opt-out of it. Even children are donors if their parents don’t opt them out. As a result, more than 99% of Austrians are organ donors. It never occurred to me that it could be the other way around.
I would be totally fine with it.
The problem is that it is factually worth a lot of money. Saving a life, either through an organ or by blood donations because they’re needed for surgery, is nearly impossible to evaluate.
And lots of people need stuff that isn’t blood or organs. If I need a car, or place to live and someone in society dies and has a car or a place to live and that’s not being given to me, but instead it’s turned into cash and assets.
That’s asymmetric.
Now I’m not saying I’m entitled that society should just give me everything I want. So I wouldn’t call it “unfair”.
But on the other hand, giving away organs and blood, completely for free, is a bit much.
That’s why I’m against it.
