Plus, it's a complete aerial surveillance network for wildnerness. What it doesn't prevent in fires it makes up for in policing and governance. Fire marshalls and fire codes have been used for warrantless searches on activists for decades because they have fewer restrictions than police. I once met an environmental investigator in government who was regularly brought in by regional police to do drone flyovers with FLIR/IR looking for grow ops and do paralell construction when they were more illegal as well.

Wildfire suppression is a super interesting use case for drones, and one that could scale to much larger UAVs, though the business case for them is plausibly closer to the more general enforcement case.
