Well, it depends on expense, doesn't it? If everyone was doing proper encrypted comms then the NSA's "job" would be prohibitively expensive: they'd have to pick their targets.

But yeah, if you really need security, build your own kit, airgap, one-time pads (stenography is to hide the fact of the encryption) and faraday cages. And worry more about informants, because now you're a target!
