Except they can't. You have to get FDA approval and jump through regulatory capture hoops. Even for drugs already approved on on the market. See Martin Skrelli's case of a generic medication easily made in science class. Sure it was cheap and easy to make but only his company had the FDA approval to sell it and the cost for a competitor to get approval was significantly higher than any potential profit.

People will die, that's the system we have. The only question is do we relent and give in to what amounts to terrorist demands?
