This is mostly trekking related evacuation, which is far easy and lower impact. EBC is about 100x cheaper overall per person than summit attempts, if not 500x.

The "Everest Economy" is worth around $500 million annually.

For other mountains with dry summits in the summers, I would agree: the effects of erosion are frightening
