It is frustrating. Rolling back forever chemical regulations is analogous to reintroducing leaded gasoline. Should we be expected to debate and weigh the pros and cons of leaded gasoline? Some things require nuance, but some things are clearly and unambiguously bad. PFAS have well known health risks, they're persistent, bio-accumulative, and linked to cancers and endocrine disruption. We should err on the side of caution. An angry reaction against this is justified. It's insanity.

That’s the argument—yes. Consumers are supposed to educate themselves about all the industries in their backyard before buying a house to make sure that none of them have ever dumped PFAS in the last 100 years. And also they need to move to a place where it doesn’t rain, because PFAS is also in the water cycle. If nobody does that then the free market has spoken.
