If organizations such as the NSA continue to be allowed to exist, then you are certainly right. But as long as you live in a democracy, you have the "obligation" to elect the people who will represent your will, that is your responsibility.
I'd happily settle for a situation where national intelligence agencies try to collect everything they can about everybody. But it's not just that, it's dozens of government agencies at various levels and with various levels of competence, plus hundreds of private actors who have some way of tracking something about you.
NSA shmaNSA - I'm much more concerned about the traffic cams in my city, installed by I-get-paid-by-the-hour consultants or barely competent public servants, who are supposed to follow all the so-called 'laws' and 'procedures' when it comes to storage time frames, access control etc.; let alone the fact that we're being watched 24/7 by itself. In 5 years time, HD cams will be so cheap that it becomes feasible for a private party to plaster a whole city with them (and many parties will do this). Slap on some facial recognition, boom we have untrackable private parties keeping logs of where every single person walks in all public spaces. And hey, storage space is cheap, let's keep all that data.
That is the real, practically relevant threat, not a government agency stepping out of its bounds. And the scary thing is that there is no realistic way to avoid that situation. Some legislation can keep it at bay for a decade maybe, but long term - we'll have to adapt to the fact that 'privacy' as it existed in the past is gone.
And that power has to raise aside from the governments agencies. I know it might affect startups too, but the people who have gathered data until now haven't stuck to enough ethics. The danger that data collection represents is proportional to the square of the size of the db, or of the compatible systems the data can be bound to.
Right, it's gonna be the theme of the decade.
More importantly, wait until these HD cams and other video cameras are hacked so that someone else besides the consultants, government, and myriad other actors has complete control. Straight out of a dystopia trope.
Besides states, there is a growing number of companies that engage in surveillance - search engines, social sites, defense contractors, companies supplying MPAA IP addresses to sue, etc.
We are in a world where there are many parties doing surveillance. The cat is really out of the bag.
NSA can just say: ok, suppose we stop surveillance - then we can't defend you against other countries doing surveillance on us. It's an arms race and it doesn't matter who started it.
