But what should I use if I am a politician and fundamentally believe that the government should be able to read my communications?
Does such a person exist? And if so, then just do all your communication using existing means like email and blogs.
I know this will never happen in real life but I think this is the only way to solve the problem of corrupt officials and revolving doors / lobbyist problems.
Edit: the book "Haze" by L.E. Modesitt Jr. has a good take on this.
