It is a bit of a stretch, sure. But it is also debatable about how anemic a person has to become before you'd find medical treatment acceptable to maintain quality of life. I know I'd jump at the chance to live at 45% instead of the low 30s! It would improve my life so much. I'm not sure there is a clear place to draw the line, but I find it easier and more defendable to draw the line at how high we allow people to boost rather than drawing the line at how low one must be before what they have is a true medical condition that it is legitimate to treat.
Making things "even" is a slippery slope argument IMO; I know you are not making this argument and I made an absurd analogy but one could start taking things a step further in determining what is fair.
I agree it is a slippery slope. But one exists on your side of the argument as well: do you allow people to correct their eyes or must they just race with the eyesight they were born with? Do you allow them to have surgeries to correct less than perfectly formed bone structure or wear devices that even out their leg lengths or must they just race with what their genes have given them?
And so on... and because we are ignoring the "safety" argument for a minute and just focussing on the "fairness" argument, I see no real clear difference between allowing certain medical treatments like laser eye surgery or joint repair but not others that correct deficiencies in blood production.
