The advantage of the ground station being closely located to users is very very small (assuming options are in view and not at the extreme limits). There's not really any latency to avoid, the traffic is going up and down and through a ground station either which way. The current ground stations probably have better (as in lower latency) connectivity than a telco's local exchange anyway.

Considering the high complexity of field-deploying a ground station during an emergency when several nearby ground stations are available, it's difficult to imagine why they would ever do this. Licensing for ground stations is more complex which generally prevents installing one on short notice, and because the "teleport" link requires higher total bandwidth than the consumer links it typically uses larger antennas, higher power levels, and often even a completely different band and encoding both for higher throughput and to simplify managing interference with the consumer-facing antennas.

That said, my assumption would be that Starlink offered to provide redundancy for the WiFi at this site, so while the Starlink service in the photo is not necessarily in use it does serve a function by providing some reassurance in case the telco experiences infrastructure problems subsequent to the fire (not unlikely because fire recovery involves heavy equipment, tends to destabilize hillsides, etc).
