To respond to your last question: I think the issue is that it puts a lot of power in the hands of whomever is controlling then surveillance system.
This can be bad because of rogue operators (creep spying on women, blackmail, spionage to get info for insider trading, data leaks, etc etc)
But even if you have some 'perfect system to prevent unauthorized use', and a 'perfect system to determine authorisation' (both of which are highly theoretical) the issue remains.
For you may agree with whomever controls the surveillance system currently ('the state'), but that may change.
If Donald Trump had won a second term, or successfuly stolen it, and the US was more and more transformed.. would you still be OK with the state having that capability? Same argument but in reverse with Sanders if you're a republican.
To give a concrete historical example: during the 1930's there was a census in the Netherlands. All the law abiding citizens gently filled in a form, stating the religion of their family. After all, no harm for the government to know all that, right?
Unfortunately 10 years later that government was controlled by Nazi Germany. And they knew exactly where to find the jews.
Result: 95% of Dutch Jewish citizens died during WW II. For reference, in France, where even today the state has a less detailed and precise administration, this number is 25%.
