Moxie is talking specifically about making a secure (particularly, end-to-end secure) federated communication protocol. Making insecure federated communication protocols is pretty much a solved problem, yes.

(And I'm sure some people are very happy GPG users. But the majority of email users are not and will probably never be)

Been working on a mail.ru pet projects in my teens (Moikrug), people were telling that PGP/GPG adoption was at around 8-9% in Russia in 2006.

Among corporate users, there are some rather big companies with 100% adoption. How they achieve it? With a simple policy "anybody sending unencrypted email is fired," and training to make sure that even least technically literate people on the company get it (a person is not let to handle anything until he is examined by a specialist).
