Speaking of progress, flip back through history and examine the movements, individuals and groups who have shaped our comfortable life and society.
If the authority at the time had the ability to completely invade their privacy, would they have been as effective? The truth is that the most important progress in society almost always begins outside the status quo and without privacy that status quo becomes much more difficult to disrupt.
So we all give up our privacy. Activists, judges, journalists, potential whistleblowers and so on.
Then... the current power structure will just accept disruption to their system because it's the right thing to do? They won't use their intelligence advantage to maintain the status quo? They won't use their mass of information to slander and render ineffective any opposition?
