I didn't read all of the article but the gist at the beginning is "you can't encrypt the whole message unless its for a state agency in a disaster etc"
Well screw that, The state can read and store all of your communications, and we are constantly watched by CCTV satalites and soon drones, I don't see how sending a private key, transactions or parts of the blockchain over encrypted radio is any kind of threat to the state, if they don't like it maybe they should end the fed, stop with the purchasing of billions of rounds of hollowpoints and stop going full retard because they are scaring folk.
