I think a root problem here is a lack of understanding of the modern nature of information. Nobody fully understands it yet, but here is an example of some that are less aware of its properties (users of Snapchat) and something that is obfuscating it further (Snapchat).

Encryption does not fully seal the analog hole, at best it is suitable for protecting structured groups of bits until they must be prepared for crossing the analog gate.

The only way to have exclusive control of any analog or digital property is to exclusively own all access vectors to it. Any form of communication that is not neuron-based removes this lock by necessity, permitting various external channels and receivers access.

Share freely or share nothing - possibly not just a zealous philosophy, also a honest reflection of reality.
