Can you imagine having diets having to be clinically approved by the FDA? 10 years plus billions of dollars to say you should eat less sugar.
When someone dies because they can't afford insulin, they are paying with their life for your sense of security. But! There is also a way to satisfy your desires, and satisfy mine. You buy your FDA approved drugs, and the ones that don't want to...don't. You get your security, and I get cheap medication.
Mine cost more under your model than they do now because lower volumes will drive up prices. The market further segments, only the wealthy can afford real medicines and the poor, barely able to afford medicine in the US as is are forced to risk their lives on unregulated garbage snake oil. This is just a way to kick the poor harder but with extra steps.
It's a pointless argument. This is right up there with Antivaxx and crypto enthusiasm, and it's a libertarian pipe dream. You acknowledge the lack of regulation has led to a pile of worthless garbage and your argument is let's keep doing more of that, instead of lets regulate the homeopathic medicines and male enhancements, and yes, diets. If you want to claim your diet is effective, then we should have that statement approved. It'd kill the industry because they're largely all baloney. And I'd be totally ok with that.
We live in a society, believe it or not, and yes your unregulated garbage does interact with my regulated medicine via market economics. As I explained. You're basically just arguing we accelerate the path to Elysium. That's an argument you can make, though let's be honest about it.
Out of interest, how do you feel about vaccines?
