The point is that people may undergo years of treatment at a relatively high cost before deciding to take their lives.   It's possible that a good number of these patients could be treated more effectively (and more quickly) if all medical "knowns" were truly assessed when treating them, regardless of the cost incurred (which could be a lot lower than the "approved" treatment).   This could be less costly than what exists now -- I would bet for many "drug-intensive" conditions, the cost could be a LOT lower.

If we continue on the "slippery slope" of assisted dying there will be a whole new industry for that will form.   This is a new development versus what exists now, and, although it may appear to be the compassionate option, it is not in a situation where other highly viable treatments were overlooked by the medical establishment/health care system.   This basically commoditizes life itself with genetics being central to to one's experience - a sickening thought.
