This is the crucial point that we as community are missing: yes, dragnet total surveillance is unacceptable, but it's just as unacceptable to have perfect secrecy for any entity. States MUST have the power to snoop any traffic they desire, otherwise we theoretically risk states being hijacked by small bands of effective conspirators. The trouble is not spying itself, it's that the cost of spying has become so low that states choose to spy everything by default. We need to revert to a state where all communications can be eavesdropped, but where there is non-negligible computational cost for doing it. One way might be to switch to encrypted communications for everything, but using keys that are strong enough to provide protection from wholesale dragnet surveillance, but weak enough for targeted brute-force decryption.
