I feel like this thread and the arguments contained in it are a microcosm of what's going on in the world at large right now, and also explains why people were so slow to respond. Perfect is the enemy of good, after all.
In medicine, bad is the enemy of good. Improperly studied medicine rushed into a clinical setting can make things worse and are perfectly capable of making things worse on a grand scale, regardless of how terrible people's understanding of statistics and variance are.
Doctors have the authority in many countries to prescribe it off label based on their own review of the evidence and their patient's consent. That's the best we can do right now without risking something much worse.
