Many countries around the world have natural fluoride in their groundwater (much of Europe), use other dietary sources for fluoride (salt), or have a significant dietary component that naturally contains fluoride (tea).
What makes water fluoridation good public health policy isn’t that we do it blindly; it’s that it gets balanced against demographic and geographic factors that don’t necessary apply everywhere else in the world.

It’s not a map of places with suitable concentrations of fluoride in groundwater; it shows excess amounts. To my understanding, both Switzerland and Germany have around 1.0mg/L fluoride in much of their groundwater. This puts them firmly above municipal levels in the US, but below what your map shows.
