You can opt out of climbing Everest (and most of us do), but almost nobody is opting out of buying electronics, burning fossil fuels, using plastics, etc. Half the people in the USA don't even vote, and a sizable majority of eligible blood donors don't donate -- and those are both free, and make life better in the community in which you live.
When we say "Earth is crowded", this is what we mean. We're living in an unscalable and unsustainable manner. We pretend that being just one individual of billions means the bad things we do, or the good things we don't do, aren't really our own fault.
- technological advancement lets everyone indulge in this lifestyle without those externalities, or ones that are worse
- people voluntarily dial down their consumption (of food that has flown from across the world because it’s not in season, of electronics made with rare earth metals, etc), travels, and so on.
Both seem extremely unlikely and it’s hard to keep hope.

That’s not being done in the US for consumption side-effects.
The western way of life with global capitalism just will not work, the same way that growing watermelons inside of lightbulbs is just not going to work.
You'd have to donate an awful lot of blood to make earth less crowded.
That said, according to the article, these ascensions only happen two or three days a year. So it’s not like there are 200 people summitting every day. It only happens in very rare spurts when the weather is favorable, which is around 1% of the days.
It used to be one team was allowed a permit per year, but has since evolved to be a tourist mecca:

Getting to the top of Everest by jumaring up fixed lines while sucking down 3x the volume of oxygen Hillary and Norgay used is high risk tourism.
It's not technically difficult, it doesn't require a particularly high level of fitness, it's just pointlessly dangerous. A substantial proportion of Everest climbers have negligible mountaineering experience and no real interest in the sport, they just want the bragging rights. You pay your money to an expedition company, you follow their instructions and they get you up to the death zone; whether you make it back to base camp is in the lap of the gods. About one in twenty people don't make it back. The only people I feel sorry for are the Sherpas.
This place is not a place of honor... no highly esteemed deed is commemorated here... nothing valued is here.

I wonder if the overcrowding has now increased the danger factor appeal?
It's certainly an expenditure of effort and resources, which ought to require a an impressive accomplishment to justify it, but tasks, however expensive and/or difficult, aren't accomplishments, only (at best) the cost paid for accomplishments.
