As I see it, privacy rights are inversely proportional to power over others.
It's a dangerous view... so unless you're totally inoffensive, you have no right to privacy ? Actual system think also about the same ...
So even if governments are necessary, which is questionable at best, nothing about them ought to be private. Because openness is a prerequisite for public oversight. And because despotism is totally inevitable without public oversight.
Governments are not necessary at all if we consider a population where *each individual* can self-govern itself. So far you can't get x people, make them live together without conflicts, hate, jealousy, conspiracy etc... it's human nature. Here the point I think would be more to protect oneself to be spied by governments rather than to spy on governments. To be able to live - simply to live in freedom - without tracking, constraints, control, monitoring (not only from Gov but also from other people acting as if they were the Government) is a terrible challenge nowadays. No need to go and try to hack the secrets of corporations.(which BTW have not so big secrets ...) Possibly a new form of resistance will be to try to simply ... live in a world shaped by global video-monitoring, paranoia, fear, controls, distrust, etc... Live without having to wear masks to get food or money. Live without having to make selfie of your ass to get a phone number. Life without the fear to get video-monitored by the iPhones of people in secret. Life without having to show your ID at anytime to anyone dressed in something looking as a uniform with insignia. Yet it is claimed that a society without control would result in a large criminal world where several mafias would rule and you would fear to get wounded or killed at any corner of the street. But 'Mafia' is also and before all a 'society' of control. Their controls are far more cruel than anyone can imagine. All this isn't new, the "game changer" is technology which provide evil governments the way to make the planet as a giant 'supermax'. Once again, this is probably where Cypherpunks, or others who still may have to come, may have a role to play as well... because this is all about technology (and the science behind)... one can fight against technology of controls (gps/sim/ai/pki/...) only by using an equivalent - if not superior - technology in order to defat these technologies of control.
