While an amusing bit of satire in itself, it's also a very good argument for encrypting absolutely everything. If you encrypt all transmissions rather than just "important" ones, potential eavesdroppers won't know which of your messages might contain anything of interest.
"If you encrypt all transmissions rather than just "important" ones, potential eavesdroppers won't know which of your messages might contain anything of interest." And if you don't encrypt, end your email with lots of FBI hot button words at the bottom, like bomb, cocaine, assasination, etc. Gotta keep all those big brother gov snoops occupied as well.
