Former chef charged with 14 counts of murder for selling "suicide kits"

That’s the bit that puzzles me about the chain of thought you describe on the part of the various advocacy organizations. Obviously they’d be against this sort of immiserating system; but why are they willing to ignore the interests of those who see their positions as being worse than death?

Is it some relatively optimistic assessment to the effect that the situation can be ameliorated in a useful amount of time, so action would be hasty; or an (honestly somewhat disconcerting) willingness to force some to suffer because their ongoing suffering makes for an indictment of the status quo that is harder to ignore than their medically assisted suicides would be?

I can see why they’d be a lot less happy with cases that are unendurable because people don’t care; rather than because the medical tech simply doesn’t exist; but it has the unpleasant taste of people being treated as a means to advance the cause rather than being allowed to choose their own ends(including literally).
