I'm not saying we should forbid climbing. But offering a way to make the trip without dying would be nice. Also, having a gondola that goes up there would make it easier to remove dead bodies of climbers.
Putting a set of stairs to the peak appeals to the type of person who wants to be on top of Everest, but not to the type of person who wants to climb Everest.
A set of stairs, obviously, ruins the wildness of one of the world's great wildnesses, as well as costs a lot of money for something that would likely go relatively unused.
Otherwise, as has been pointed out, you can take a helicopter to the top, but honestly, that may prove over time to be more risky than the slower way.
