I'm trying to ask something slightly different, I think. If I'm trying to have ultimate anonymity, I know that I can do things that actually expose myself. I don't want to be a giant beacon saying "I'M DOING SOMETHING SECRET".
I know almost nothing about Tor, but with radios, if you don't have the right setup and usage, encrypted traffic is easily detectable, just not as easily decrypted. So, if you are dumb, you'll broadcast *very loudly* your location, that you don't want people to know what you are doing, and other data. If I were using radios and wanted my communications to be untraceable, I would use some very specific measures and avoid others.
I'm more asking, in what cases is Tor helpful and in what cases are you worse off for using it? And I was trying to give a use-case that wasn't just advertisers.
