I don’t think anyone just randomly donates a kidney, like you would give blood
You would be wrong about that, in 2021 more than 450 people in the US anonymously donated a kidney to a non-familiy member (source). This is the scenario I’m asking about. One of the arguments given is that just as we allow monetary donations to specific groups of people, why not organs.
I thought that “altruistic organ donor” was a well understood concept, I was wrong.
You’re factually wrong on that aspect.
