If I want to sell lemonade, tea or coffee by the road, I need to apply for 5 different documents of some kind or another in my city.

If I want to manufacture (or moreso, import) things with all kinds of unknown, untested chemicals, I am free to do as I wish with no supervision.

Getting a medical device certified is much more difficult than selling beverages from a food cart.

People used to drink radium water for health benefits and think smoking wasn't a problem. Good science is reevaluating based on gained knowledge then behaving accordingly. Expect gained knowledge to lead to more strict regulation and certification standards.

Well, arguably, we understand lemonade well so we can regulate the sale of it. The same can't be said for PFAS. People move slow, and regulatory legislation, particularly under conservative rule, desperately so.
