Imagine how much better the world would be if we harvested your orgnans and gave them to a dozen people who would die without them. Yes it might be bad for you personally, like the author who starves, but think of the bigger picture.
Now imagine a world where donors can voluntarily give one of two working kidneys to people who need them to survive, and you have a much closer analogy. Still not quite there, but at least not as unnecessarily alarmist.
