European policy isn't based on modern fluoridation being dangerous, it's based on having alternative systems in place (which vary by country)
In Windsor Ontario, across from Detroit, they took fluoride out of water for nearly a decade before reversing that decision based on results: https://www.cbc.ca/news/canada/windsor/fluoride-water-system...
Maybe Utah will be a place with alternative systems, based on another thread it sounds like they have an interesting Mormon safety net. But I would hope states do pilot tests first at least. If studies show that the historic gap in dental health between fluorinated & unfluorinated communities no longer apply, then that would be data driven policy
But it seems like this policy is based on someone's common sense that you shouldn't put minerals in water
