And while I don’t think that’s exactly what you meant, it’s how it comes across. Almost all of your points are some variation of who’s gonna pay for their treatment and take care of their physical needs.

Indeed, that's not what exactly what I meant. Thanks for giving me the benefit of the doubt.

My main point can be summarized in that second to the last paragraph, which I doubt has communicated things adequately.

To reiterate: it won't be initiated by the medical professionals. They're simply there to ensure that someone applying for this procedure are indeed "proceeding of their own accord and have made sure options have been considered". The waiting period is there to make sure that not only they've arrived at this decision after careful deliberation, but also to force them to consider and try out the options available to them. The process can be terminated at any point by the patient, and the final step will not proceed without their permission.

My point is that mental illness is much less understood than physical illness, and I wouldn’t trust any diagnosis that said the condition could never be resolved.

I accept this point. This is why I‌ put the emphasis on the decision of the patient. And this is where I think our positions fundamentally differ. Promising treatments may or may not be there, may or may not be there in the immediate or far future, but it's on the patient to consider. The medical professionals are there to ensure that the patient has considered available options, and have exerted reasonable effort to improve their situation. Whether or not the patient has made "the correct decision" isn't the point—but rather whether or not the patient has made an informed and well-thought-out decision.

I share your opinion that in an ideal world, this shouldn't even be needed. That even though the option would be there for anyone to take, no one will take it in an ideal world. But we are not in such an ideal world. We can strengthen our social safety nets to help people suffering from the debilitating effects of mental illness (among other sources of suffering), and that will do a lot of good, but until we arrive at a society which no longer needs a dignified exit because no one ever wants to exit, I am of the opinion of giving them that option.
