Any high level official recommending it is a bad thing in itself. The major issue is that there isn't enough evidence there for drug companies to put in money to ramp up supply. Heck, there wasn't enough evidence for Trump, who had just signed a trillion dollar stimulus, to divert a few tens of millions of dollars to ramp up supply. Yet, you are telling a bunch of people who may never be able to make use of it to go buy the existing supply on the market. This existing supply exists because there are people who have actual proven needs of the drug, and as a result now you've also made the drug unavailable for uses where it's actually been proven to work.
