I read your comment and it strikes me as a cautionary tale that can be used by bad people to justify or push for eugenics: "they took him; they said he developed Alzheimer's".
As we're currently seeing happen: whatever is left unsaid in the body of the law can and will be abused by evil people to concentrate more power (even if the spirit of the law advocates for something kind).
So, we have to normalize some sort of stress tests for laws... because you sure don't want to be dragged against your will because you're poor.
Yes, there is a danger of that in general. I think someone made a movie in Japan about the subject, specifically because there is a culture of the elderly not wanting "to be a burden on the younger generation." Some said it hit closer to reality than science fiction because of that specific cultural characteristic in Japan. It also supports Kahnemen's position of pulling the plug when "the going is good" from a ethical point of view, since it leaves no doubt of intention.
