I find this comment somewhat disingenuous. People have been arguing about allowing more experimental end of life treatments for at least 40 years of my life. I grew up during the AIDS crisis and there were all kinds of quacks selling this or that to take easy money from desperate people. If what you say is true, then why hasn't it already happened? After all, isn't 40+ years long enough to argue about it?
Because decades of arguing in no way implies that "the truth" or correct policy will fall out of politics. Abortion and marijuana legalization are two contemporary (and much more prominent) examples.
