I think also underappreciated is that Starlink can be used for purposes other than communication. It's already physically capable of acting as a giant radar, and SpaceX has gotten a missile tracking contract, and the E-7 wedgetail radar plane has been cancelled, which the DoD had publicly said was because it is obsolete given what's possible from space. It could be that they're planning on launching another radar constellation, but my guess is that it's already up there and it's called Starlink.
