That's the easy one: then everyone climbing Everest automatically becomes an outlaw when they die it removes those criminals from the society and saves a ton on police and courts and jails. A clear win-win.
Thankfully the fees provide enoughincentivecorruption for Nepalese government to not go there.
What the Nepalese gov can do is allow fewer guided expeditions and issue fewer permits to those expeditions. This would reduce the number of people on Everest who could never make it without a guide.
