I get your point but in the grand scheme of things very few people require mountain rescue services.
That's kind of my point.
If huge, huge numbers of people every winter were requiring hospitalization for some ridiculous winter sport, to the point that hospital services were being significantly taken up with them for several months and other operations and procedures were being delayed or cancelled to make room for the sports injury patients, trust me, we'd either see the banhammer being wielded over the sport in question, or we'd see demands for the sports enthusiasts themselves to be billed for their treatment.
I agree it could be a slippery slope, but then everything we've done over the past 22 months is a slippery slope. School closures are a slippery slope (what's to stop them happening again and again?), lockdowns are a slippery slope (what if they become normalized as a way to deal with all sorts of things)....
It's not clear why the NHS is the only institution in the UK which is somehow expected to function according to the same rules as normal, even in a pandemic.
I think that if we see significant difficulties next winter, there will be a strong push to "do something" about the vax refusers-either billing them or pushing them to the bottom of the treatment queue. I know it seems a bit shocking now, but then I never ever imagined we'd have vax passports and things like that eitherthe idea would have been shocking to me a year ago. I think it will happen, should the NHS continue to struggle next winter. People's patience will have run out.
I'm hoping that by next winter the worst difficulties will be over, however, as the whole population will probably have enough immunity to "mostly" prevent severe disease.
