I've just had a simple idea while thinking about the conflict between privacy, freedom, law and democracy and its effect on the Internet. How about designing a new set of protocols that would be using the highest degree of available cryptography and obfuscation, minimizing leaking of traceable information, but having a democratic voting mechanism in its core (Paxos-style?) for "de-privacing" sources of information/traffic shall the majority of users decide (in cases clearly violating laws in grave matters etc.)? Direct democracy-style. How much of a pipe-dream would that be? What would be deficiencies of this approach and how could they be addressed? Is this even technically doable in a de-centralized fashion? Would apathy or malice of general population be the main risk?

The motivation is that nobody would like to have all their private matters out in the open (which is a fact nowadays), but we need an efficient way to enforce reasonable laws (like preventing child abuse, selling hard drugs, illegal arms etc).
