It's not about being medically difficult to care for. It's about being impossible to properly predict that they won't get better. That means that you would be providing death under false pretenses. That's my problem with this.
In terms of your question, I'll answer with two things about the people who don't get better.
The people who have those lengthy trials, and who have suffered that long, I will remind you that we have no legislative safeguards that actually require that. Dr. Gupta's expert panel explicitly said that they are not recommending any additional legislative safeguards.
That is remarkable, because anything else just becomes suggestions and reassurances. Even Dr. Li, the scientific lead for CAMAP has said this.
