Water and power are local issues. And data center use of water and power is already, currently having local impact on politics. I saw ads about it during the election cycle that just concluded. Candidates had to answer questions about it at debates and in interviews.

People are using these arguments for the simple reason that they demonstrably resonate with average people who live near data centers.

They probably don’t resonate with people who have plenty of income and/or do not compete with data centers locally for resources.
