From a conversation elsewhere...

If you have a cell phone, you have a remotely activatable microphone with a GPS locator on your person. It doesn’t have to be a smartphone, either. If you haven’t been conducting yourself accordingly since about the time Clancy released Clear and Present Danger, I don’t know what to say.

Also, if I were an information-hungry oppressive government, I totally wouldn't pay special attention to the person who refused to own a smart phone or a credit card or "smart speaker" and did all their transactions in cash. That wouldn't be super conspicuous at all.

We learned a long time ago that black was a lousy color for night camouflage because "nothing" stands out from a background of "something".
