“But you know, the DHS has said that people who use cash are “potential terrorists” or to be automatically suspected of being up to something illegal.”
Indeed, and the wife and I are already transitioning to just plain cash.
For no other reason than to tick off the govt dorks.
As for comms, someone come up with a good means of encasing msgs in pictures (some random collection of LSBs in the pic would work....albeit with the warning that that randomess heeds to change). Keep the picture flow going - overload them.

It’s true that the commercial data miners use the “metadata” from your card purchases to learn all about you. It’s OK to buy groceries or change your oil with a card, but certainly make all purchases of “other” items in cash if possible. Things that you don’t want them to know about.
Already out there. Steganograpy is fairly advanced, considering. One of the beauties of steganography is that you can, to some extent, foil their traffic analysis. Link to a pic with encrypted data here on FR, and there is no real way for them to determine who the actual intended target is. Same thing for uploading the pic to facebook.
