"If everything's encrypted, what's the problem?"

Because a lot can be made out even from the metadata. The one thing that CAN'T be encrypted is the packet headers etc - the network itself knows source, destination, volume and timing of messages, and a lot can be determined from that. For example feed a juicy bit of (mis)information to a known point on the network and note where subsequent messages are directed
