In principle agree with Carey. You have to allow adults to make really bad choices.
Yes. She's talking about adults, not children, which is less of a challenge to me personally.
That said, I don't see how want rather than need can apply in the UK context of universal healthcare so I would say Carey's argument here is US-specific.
Also, yes, she's talking about adults. But, since cognitive development is not complete until about age 25, I think the NHS needs to have a very strong conversation about what constitutes an adult in this specific context.
(Also, no dig at you personally - just expressing deep, deep frustration.)
