I have banned it personally by happenstance and by choice. I have never lived in a city. My own well water only. I am never without my personal water bottle. I've only consumed very minor amounts of fluoridated water, like a few sips in a restaurant, etc. I don't drink soda or beer or any manufactured beverages except a little wine once in a while. I have never gotten a fluoride treatment from a dentist. I have mostly used non-fluoride toothpaste or baking soda.
