> To play EA's advocate: if you assume that donating the kidney will "save" a life, then if you had 4,000 kidneys, you could, on average, sacrifice yourself to "save" 4,000 lives.

No, see, this is what I mean when I say that maths are being misapplied. We know how many kidneys you can donate before you die: two. Or three if you have three. Some people even have four. So what does the "4000" have to do with that? The "4000" is the number of different people who each donated one kidney, so it doesn't tell us anything about one person donating 4000 kidneys.

And anyway, if you need to imagine a person with 4000 kidneys before you can figure out the value of live kidney donation, then you don't have a good way to figure out the value of live kidney donation. Which is my point.
