To your point about email, wouldn't it be easy enough to install a browser add-on that handles the end-user PGP for you? Even people who don't understand all this encryption stuff could do it. "For safer surfing, install the SafeSurf extension and then no one can spy on what you write!" I suspect that eventually, and to the chagrin of the spies, most of us will have this type of extension installed, and share public keys with our correspondents or whatever. Then the next big market will be databases of public keys, but luckily those can be altered easily enough. In fact, make the extension automatically prompt you for a new one every 4 weeks.
