When, for any given thing you want to regulate, there are 4 incredibly wealthy special interest groups trying to warp your message to protect the profit margins of the companies they represent, rather than keep safety or anything else in mind there, making sure that you don't take "Totally reasonable measure A" and get the people you're protecting messaged, "HOW DARE YOU, MY FREEEEDOM!" - that's quite difficult.
But despite my understanding of that, the HUGE problem there is that "Totally reasonable measure A" and "Draconian Evil Measure X" look almost exactly the same to us onlookers, and when the FDA, or anyone, uses "Morally Ambiguous Embargo Y" to protect their actions, why, the rational response from us as onlookers is the ASSUME that they're performing "Draconian Evil Measure X."
So what, exactly, is the answer? I don't think there IS one presently out there that isn't incredibly messy, but I hope we can still discover it - that is, figure out how to protect the almost certainly true and reasonable actions from the 'bad guys,' while not falling afoul of the rational reaction of the 'good guys' (us, in this case, the people being protected) and coming under attack from THEM.
