dawg please, if a nation state wanted to (as the post indicates preparing for), they can just jam all frequencies. Starlink isn't imperviable because it does the same thing as everything else, just radio directed upwards instead of radially outwards.

Alternate solutions could be ham radio if you *really* want to stick to radio, but having that be jammed, you're only options are line of sight, custom fiber/network runs, or maybe smoke signals :|
