> Would this not also open the door for any snakeoil salesman to prey on what might be medically "hopeless" cases?
If you're diagnosed with something uncurable, then by definition you have a doctor or a medical team that has performed the diagnosis and is overseeing your treatment. There is, invariably, some form of treatment; in extremis, even "here, I've booked you into a hospice where they're going to load you up on opiates" is a form of treatment.
Any experimental drugs you're administered would go through your doctor or medical team. If those drugs are transparently snake oil, they should usually be very strongly advised against. If they have a halfway plausible mechanism, doc will probably say, "go ahead, roll the dice."
In any case, the snake oil salesmen aren't preying on sick people alone -- it's the sick person, plus the professionals who are in his corner, plus family and friends, etc. I don't think it would necessarily be trivial to make lots of money peddling something known to have no efficacy.
On a much more general philosophical note, there was much debate in Ancient China between Legalists, who viewed humanity as inherently evil, and Confucianists, who viewed humanity as inherently good. Where you come down in this debate seems to depends on that view. If you believe that men are inherently evil wreckers, you need stringent and indeed draconian regulations to keep them in place. If you believe that men are good, and that lives saved are on balance the greater aim, you should argue against draconian regulations and limitations on treatments.
The obvious case is that some are evil and some are good. And that's enough for the evil people to find the good people. (This is how Internet-connected computers secure works / fails.)
