So basically communicating online only with people that will use pubkey-crypto? I think that's a needless extreme. Also, what happens when everyone does that and the government makes crypto illegal? You're back to the original problem, the abusive government. That being said, I did just suggest encryption in an earlier post today... but that was before I started getting the feeling this problem goes deeper into the government than just a small gov-agency & some cellphone companies.
The problem with PGP is that friction is in every message you send. For every email you have to make the decision about encrypting the message and entering your passphrase. It's a hassle.
The reason I recommend Bitmessage is because after overcoming the friction of installing it, it's frictionless. You don't have to remember passphrases or anything. It also has advantages over PGP-encrypted email like deniability, built-in spam minimization, broadcast messages (like Twitter), chan boards, etc.
