If it actually helped the economies flourish, then that would be interesting. NIMBY is in some part a reaction to the belief (likely true) that there would be neither jobs nor tax money from a data center in their community backyard--it's all downside with no upside.

The Loudoun county has Datacenters that pay enough in taxes equalling the salary of 30k residents earning $40k dollars each (in a county of ~400k population).

This is a shockingly high upside relative to any other industry, like Car or Steel industry which pollute way more.

These taxes can be used to create better infra and have other things going on. Better schools and maybe even research facilities.

But I do think the opposition is largely ideological in nature so these arguments don't matter at the end.
