People might say that they want security, but when some logical person takes this literally and respond “Use PGP”, they might be logically correct (since as bad as it may be, there might not be any secure alternative to PGP), this advice will always be ignored because what people want is not actually security. What people want is to feel secure while not changing anything about what they are doing or how they are doing it.
For an excellent argument of why most people shouldn't do that, I recommend the essay "epistemic learned helplessness": https://web.archive.org/web/20180406150429/https://squid314....
The gist is that most people are so bad at evaluating logical arguments that they are more likely to be swayed by false arguments rather than correct ones, so the winning strategy is to simply ignore everything that sounds strange.
