If you're determined to climb into the death zone without supplemental oxygen, you could still carry a small cylinder as a bailout option. Hell, if you want to make the climb really challenging, you could carry ten oxygen cylinders and a Piñata.
More to the point, you could just not climb Everest. Other than the altitude, there's nothing particularly interesting about the climb. The Nürburgring was the most interesting and challenging course in the Formula 1 world championship, but the sport abandoned it in 1976 because it couldn't be made safe. The drivers agreed that no race track was worth creating widows and orphans for.
Minor quibble: you mean aid climbing, here. post-1960ish, "french-free" or hangdog ascents are considered bad form for trad, and using your gear to take your weight is an ethics violation at some level.

Motorcyclists, of course, continue to use the Isle of Man TT course despite the deaths of 255 people to date.
