Don't Look Up is about ignoring expert consensus on a clear threat, not about rejecting benefits out of fear. For the analogy to land, you'd need overwhelming evidence that these data centers are net-positive for host communities, but that's exactly what's in dispute.
You're right that there's tension between 'not enough power' and 'no new heavy loads' but it's not hypocritical to argue that megawatts of power should be allocated towards 7k jobs rather than a few dozen if possible. That's exactly the kind of tradeoff a power-constrained state should be explicitly making. The logic behind it is not satirical, it's just triage.
On top of that, this is not a blanket ban of AI datacenters. It's a temporary blocking of any new datacenters that require more than 20 megawatts until late 2027 pending a PUC study on how these datacenters will affect their existing grid. It also creates a new council for researching and coordinating the creation of new datacenters, so this really doesn't seem like any sort of NIMBY action here.
Honestly the only major issue I have with the bill is that it neglects to distinguish self-powered facilities that don't provide much strain on the grid. Though it could be argued that water consumption of these centers might be the reason for it.
