Communities passed and paid bonds to have water hookusp. Built infrastructure. They should have a say in who gets access and why. There are plenty of places datacenters could build without hassle, but they want access to readymade infra, and that comes with a reasonable tradeoff.
There are also traffic issues--likely less of an issue with datacenters or solar farms. But things like housing that put pressures on local schools are certainly issues--though again not really with datacenters which are more about power and water infrastructure.
