> And they could "disrupt" them as well with a cheap signal jammer near the receiver. Amateurs aren't running around the country placing transmitters near all the government comms. Also there's many types of encryption (onion routing for example) that depend on being able to intercept communications at multiple locations. Also there's still metadata that can be learned even without being able to read the comms directly, for example who's broadcasting at any moment. Even amateurs were able to figure out when Russia was launching missiles at Ukraine even from their encrypted comms, if you have a more advanced surveillance system in-country you can learn a lot more.
