Yes, that's a great example of a success story. However, other drugs have gone through the same process and were eventually found to not be as effective as during the trial; or worse, they were found to be dangerous. Aside from the threat to the patients, there's the opportunity cost of such "misfires." In the US, we can upon death donate our organs to others in need. We can also, again upon death, donate our bodies to science. Yet while alive, we can't decide to help ourselves, and ideally others as well? That doesn't make sense.
