DC's are being used as a proxy for power and wealth disparity. Fix that. Have an actual measurable plan for general prosperity (health care, QoL, housing, you name it) and the data centers won't be a concern

The issues you listed seem intractable in the U.S., and the current NIMBYism towards data centers seems likely to make NIMBYism towards housing even worse - a number of the same arguments that were used against housing are now being used against DCs, but we’re seeing a whole new level of NIMBY tactics being tried out - I expect we will see similar city-wide/county-wide bans on multi-family housing, mass transit, mixed zoning, etc - or use of eminent domain to block housing projects, etc. if this kind of NIMBYism becomes accepted or even celebrated against DCs.

Or for your suggestion to “fix healthcare” - how and by whom? The solutions that those on the left push are anathema to 1 of the 2 major parties in the U.S., and the party which currently controls all of the branches of government.

Pretty much, disrupting datacenter builds is one of the few ways people can fight back against evil tech billionaires.
