So restraining surgeons with pesky things like ethics would fall into that then.
The sad thing about the fingers guy is that our brain's perception of the body is malleable. I read a fascinating book called "Livewired" by David Eagleman which was all about how our brains respond to sensory input and adapt to the loss of inputs, how our brain's model of the body can adapt to e.g. limb loss, or enhancement (not just biomechanic artificial limbs and other sense but also how our brain flexibly adapts to different models of inputs and outputs, e.g. learning to drive, adapting to drive on the opposite side of the road in foreign countries, flipping between the two, learning to cycle, rollerskate etc. )
I'd be really surprised if there wasn't a way of reintegrating the healthy fingers back into this guy's body map so they felt like part of him again.
But even leaving that aside, how could they be sure that he wouldn't have woken up from surgery horrified with the reality and irreversibility of what they had done. Or how could they be sure that the pattern of intrusive OCD thoughts about his fingers that had been whirring round his head wouldn't just transfer to another body part? It seems so reckless. 7 months of alternative treatment doesn't feel very long considering how people can recover after years of mental illness with good therapy.
I used to be supportive of assisted dying a la what Terry Pratchett and others called for. I thought of how it is seen as a necessary kindness with pets etc and seemed cruel to deny that to people.
But Canada's MAID has really challenged that for me, especially combined with the medical transitioning on the gender stuff. It seems rather too convenient when combined with the medical experiments they are doing with gender transition. Mess up people's healthy bodies and no worries if they regret ending up as a lifelong medical patient, they can always take advantage of MAID 😔
I'm also really aware having had depression before that things can seem like they'll never get better but then they do. Or people who suffer disabilities initially can't imagine enjoying life again with their new limitations but then do.
In general being online and relatively in control of how others perceive us (curated feeds, filtered images, avatars etc) I think results in more living in our heads instead of in our whole bodies and having reduced tolerance/familiarity for the messier bits of our physical lives.
There's a line or two in Sir Ken Robinson's TED talks about educating kids like they are floating heads/brains rather than whole bodies.
