The problem is that a lot of places, there is plenty of fresh water. However, when we start using a lot of fresh water (in this case for datacenters), then those supplies runs low.
Sure, we could spend a lot more money on making sea water drinkable or we could just use less water for purposes that are not as important / that could use sea water / that could use alternative ways of working. Also, not everyone is close an ocean and that would mean you have to transport the water over long distances - not impossible but it adds to the price tag.

I hate that damn price tag.
