And what many don't realize is we have airborne SIGINT aircraft all over the world. Things like USAF Rivet Joint RC-135's sniffing for signals for many miles around. No telling what ground based sniffers are in place in larger populations. And add on jamming capability, especially for citizen bands like CB, short wave and cell phones, and we're basically at the mercy of those with the tech to shut it down or listen in at every moment. Cell phones microphones, smart TV's, Alexa devices, basically anything connected to the web with a microphone is listening.

People fool themselves if they think they can communicate without some way to listen, monitor or absorb that data, pool it, analyze it, etc. That's why the NSA built that giant facility in Nevada. Storage. And computing power. Go talk in the woods without electronics if you're looking for the perfect solution.
