Peter, I think that the doctors caring for Tafida would be, and would be correct in being, pretty affronted by the accusation that - like some dis-functioning gadget they think that she needs to be “got rid of”.
One of the hardest things in medicine is to know when further treatment is futile and not in the interests of the patient - do not underestimate the emotional burden of such a decision unless you have had to make it personally, vanishingly few doctors make that sort of decision lightly.
OK, I’d half agree with that - the body’s natural ability to heal is a huge factor in recovering from any illness - but does the body naturally excise a cancer or is it the surgeon? If the sepsis is overwhelming does the body naturally manufacture broad spectrum antibiotics to overcome it?
And where doctors cannot heal they can treat, ameliorate and palliate - adding years to life and life to years.
Your comment seems to relegate the medical profession to a very minor role in healing and the management of illness. That might have been fair in the middle ages, the Victorian era or even in the first half of the 20th century but it is increasingly a false view of medicine and what it can achieve.
