Can the downvoter show his face and elaborate? Thanks
I wasn't the downvoter, but I suspect they may have been pointing out you are missing the forest for the trees. "The people" don't need detailed explanations about why one form of technology is "more secure" than another. Instead they need motivation to care about security from their government.
Security and "being able to sleep" is more about understanding, and less about installing things on your PC. If everyone suddenly started encrypting their emails, of course we would be safer. But nobody is going to bother doing that, if they don't really feel safe (because they don't understand how safe they are, or which risks they are taking).
TL;DR - To sum up, even if you get people to want privacy, there is quite more work to do after that. People have lives to live, and if the cost of privacy is becoming a security expert, in most cases they won't bother.
