That's actually *NOT* how it works at all. That's how the public believed the system worked pre-Snowden. Now it is clear that all data is monitored and parsed. There is no suspecting of wrongdoing or lawbreaking, there is no targeting of "bad people," there is simply monitoring and tracking of everyone at all times online.
I'm opposed to such a system, regardless of a bad tyrant leader, but just imagine what a bad tyrant Hitler type leader would do with that type of information on everyone. There could be no resistance. And Hitler was elected. Again, I'm not paranoid about another Hitler--I think this is wrong regardless, but I'm just saying the consequences of that type of ruler coming to power would be disastrous.
And to your first point, some of us don't want or need that kind of "protection" thank you very much
