Says who?

Biology. Dying from a cerebral oedema is one way your body tells you "you shouldn't have come here". Rushing quickly up that kind of altitude is dangerous to your health - for example, one of the biggest contributors to altitude medicine was when India rushed an army to the Himalayas in the '60s to counter China [1]. They got a lot of pulmonary and cerebral oedemas, and the sizable affected population really helped the literature in the topic.

Also, keep in mind that the opinion offered was in response to someone basically saying that it was indefensible to not build a gondola ride to the top of everest. I notice you didn't tell that commenter "says who?".

Nonsense, people fly everyday, they're called pressurized cabins; that you think anyone is suggesting otherwise is your lack of imagination, not some limitation of biology.
