Yo, crypto-heads. Encrypted communication doesn’t protect your privacy. Laws protect your privacy, and democratic oversight of lawmakers, so you can ensure those laws stay. A tyrannical government can easily do any of the following:

• ban strong encryption if not all encryption;
  
• mandate backdoors into encrypted communication systems;
  
• force people to unlock their encrypted media, even without a warrant.
  

What do you mean, all that is already happening, and in supposedly democratic countries, not some dictatorship?
