Assuming an individual is independently wealthy and has enough income to arrange for all the additional assistance they will need after removing both legs above the knee, the highlighted bit makes perfect sense. Otherwise, they will have to rely on family, friends, neighbors, and/or government assistance significantly more than they did when fully ambulatory.
Actually the very thought of someone actually doing something like that --- and the thought comes graphically to mind, as I read your post and type out my response --- kind of makes my stomach turn, an actual (if very slight, because completely impersonal) vertiginous, nauseated reaction. ..........But, once again, someone else's body part, then their call, not mine; and my reaction is compeletely irrelevant. (And no doubt the reaction is partly because one isn't used to this sort of thing. Should people come out and start doing it, then no doubt the rest of us will get used to it without feeling queasy every time we hear of something like this.)
You're right, such a person naturally becomes more dependent on others, provided their own income isn't enough to compensate for it, and maybe to an extent even if they're wealthy enough. But, while that's a fair point, and a point that a candidate for this sort of thing needs to very carefully understand and consider and evaluate before pulling the plug, but I'm not sure how it's relevant to anything beyond that. Their friends are family are well within their rights to not want to put themselves out to accommodate this sort of thing; and equally within their rights to want to reach out and provide assistance. Their business, their call. I agree, this ...person, can't
demand of family and friends that they help them, they haven't that right, I don't think.
That state though? I don't know. While this person wouldn't have any rights per se over their family, IMV --- unless they were legally dependent on them for some reason --- but the state, well, I really don't know. On one hand, I agree, they shouldn't have any right to make demands on me and my pocket directly. On the other hand, one of the functions of the state is to step in to provide assistance that is warranted, and that individual taxpayers may not necessarily be willing to provide. So is this "warranted"? I don't know! The question of whether the state should actually provide any assistance in this kind of a case is ...well, something that is debatable, with things to be said on both sides of the issue.

Ah, right, edit window's still open, good. You know what, I've made up my mind. That is, had I been asked to vote on this issue, on whether the state should support body-dysmorphs (don't know if that term's actually used, but whatever), well then I'd have not voted at all, back when I wrote that comment, because I was undecided, totally undecided. But I've made up my mind now, and the answer's a Yes. The state should, indeed, support these dysmorphs. I mean, not necessarily go out and offer them support that no one else gets, no; but any support, any assistance, than disabled folks generally get, these dysmorph-disabled people also should be eligible for, that's my considered view now, and that's how I'd vote, if it came to that. (Open to changing my mind, given new facts and better arguments, as always; but as things stand I'm pretty sure how I feel about this now.)
