What the author doesn't seem to understand is that alpine ascents in general aren't done in the form of organized competitions, so the entire comparison to anti-doping regulations in sports is quite absurd: you can't tell people what not to do when they do it independently, unless oxygen is somehow universally made illegal. Even WADA can't tell you what substances not to use when you are cycling/running/doing-whatever on your own free time. There is no "Paradox of Doping" in mountain climbing: it's the same as in any other activity that is done independently - you can use equipment that will make it easier for you, but then others might not feel as impressed.
