Except for the fact that there are no known space-based DEWs, and they would need to have major power levels (e.g., megawatts) in order to be effective on terrestrial targets. This imposes certain required sizes (meter-wide directing telescope) and masses (thousands of kg for operating fuel). Also, they would have to be in an orbit that crosses Hawaii...but would be overhead for only a matter of minutes. Oh, yes, and the skies must be clear of clouds (and smoke), as lasers penetrate them only poorly, and can't see their target through them.

This is a bunk idea.

1. DEWs are real, but they are terrestrial and only in service for test.
2. If the Deep State is getting its ass kicked and has access to machine guns, napalm bombs, and nuclear weapons, why would they NOT use them? (You don't construct an argument FOR item X by posing questions of WHY NOT item X.) A space-based laser would be there for only a classified mission, and you would not compromise such an asset by using it for a cheap thrill and spending its limited burn time reservoir.
3. Too bad for Lahaina, but we have already experienced past forest fires covering far more territory in Washington, Oregon, and California. Some of which have been proven to be caused by arsonists. (Maui has a land area of 727 square miles. The land fires in 2022 burned 11,839 square miles.) Why use super-technology when good old-fashioned arson works just dandy?

As for using DEWs---

1. You don't need "laser precision" to wipe out an entire island. Any number of fire bombs would do nicely.
2. Perhaps you haven't heard how arsonists use items like phosphorus, magnesium, and/or accelerants to ignite and promote the rapid expansion of an all-consuming fire.
3. No reason for arsonists to "run around" if they are pre-positioned.
4. Investigators would never conclude it was a DEW. No evidence.
