Well it's a bit of a "canary in a coal mine" scenario. I'd be very wary of subjecting my family to unproven treatments. And as 'condorlover1' and 'olkolfri' rightly state above, we live in a very litigious society. To "take a leap of faith" in a medical-professional sense is to open yourself up to significant liability. Patients themselves are potential litigants.
I agree. For example, the current administration is silencing scientists who, in agreement with the worldwide scientific consensus, argue that climate change is real. It's a perfect example of your statement. But I'm unclear how this applies to the drug in question. Are you suggesting that the government is somehow suppressing results or trying to hoard the drug for itself?
I understand this is a fear of many people. Being "ruled" by a "scientific-technological elite." I have to say that we've done a pretty outstanding job of ignoring science in this country, and the beautiful mess we're in at the moment is a direct consequence of that. My fear is the exact opposite: being ruled by unqualified people who surround themselves by other equally unqualified individuals. Prayer and bravado is no substitute for informed planning and preparedness. In the present situation public policy is in fact the captive of Wall Street, and science is an inconvenience if it stands in the way of profit and public safety.
I have no problem with the public getting involved. There are clinical trials that people can enroll in. Then there are people like the Arizona fellow who poisoned himself and his wife with chloroquine aquarium cleaner [1]. This is what people are trying to avoid happening on a larger scale. If people want to advocate self-experimentation with potentially unsafe treatments they do so at their own risk. You have to assume at some point that medical professionals have your health and safety in mind when they make rules like this. If people have the attitude that they're an elite that's suppressing the truth or somehow trying to control them it becomes very difficult to create policy that people will adhere to. The pharmaceutical industry, on the other hand, has as a motive profits. That's a different animal altogether. I'm talking about public health officials and health care workers.
