Are you sure fluoride doesn't? It does accumulate in the soil, building up in crops. Considering fluoride exposure from all sources, many people are above upper safe limits, even from tea drinking alone

I don't think fluoride should be added to water as it just pollutes the environment, where 99.99% of water isn't coming in contact with teeth

It doesn't. This is high-school chemistry.

Fluoride only "accumulates" up to the peak concentration of the environment (no further) on places where it is removed from contact with that environment.

You can only accumulate fluoride in the soil if you keep adding it and there is almost no rain to wash it away.

Like how crops are irrigated with town water, and in many areas with lowering rainfall? Accumulates in fruit, vegetables, leaves too

Yes, irrigation with the minimum possible amount of water is known to destroy land for millennia at this point. But sodium will be a problem way before you notice any change in fluoride.
