How about not mounting publicly funded rescue missions at all? You can pay for insurance if you want someone to risk their life to come get you.

they already do this. theres a huge amount of luck that factors into a summit for a ton of climbs. they spend weeks just acclimating let alone the amount of preparation prior to their climbs (and the fact that people who want to just pay to summit are not physically capable or even allowed up, theres actual physical confrontations by guides to head back more often than you'd think).

theres a reason people are left for dead and walk back to camps in the middle of the night (beck weathers is the de facto example) and its because they are so incredibly competent and prepared that they are able to survive but at extreme costs to themselves and those around
