@why does everyone moan about a lack of privacy
Have you heard of "Freedom of Association?" In short, it's the right to hang around with whomever you want, for whatever reason you want, without someone suspecting you of a crime due merely to the fact that you are gathering in a group, or who you may be associating with.
There are lots of examples where monitoring who associates with whom, and where can lead to revealing sensitive information that can damage the lives of law abiding citizens.
Let's say that several employees from a company are seen meeting with a representative of a Union. It could then be assumed they were trying to unionise their workplace, or perhaps it could be assumed they were seeking to leave their workplace, and take up elsewhere. A dozen other assumptions can also be made. This is only one small example, but many more exist.
If everyone can see who you hang out with, when and where, then the only activities that become allowed are those that benefit those in power. If you step over the line, just a little, word will spread, and you will lose.
Constant monitoring by the police is a short step to constant monitoring by employers, parents, spouses, etc. Any information made available to the cops can be made available anywhere else for a fee.
When I gather in public, sometimes I am gathering in a place, and at a time specifically to avoid other entanglements. Sometimes no one owns property large enough to hold an assembly of all those I would spend my time with, and yet we do still expect privacy and a freedom to assemble anonymously, should we choose. If every bar, strip club and fetish shop must monitor everyone, how long then until every hotel must as well? How long before you can not rent time at a convention centre or a conference room without your details being recorded?
In that society, where do you go then if you want to unionise? Or what if you want that secret tryst with the secretary, or want to arrange to see that rare collectible sports card or anniversary gift without your spouse or parents knowing? How about living a fantasy? Changing your name for a weekend, paying in cash at a hotel, and pretending to be someone you're not, just to see how the other side lives? Many fantasies, or business issues, personal issues and so forth simply can't occur without a reasonable expectation of privacy and a certain level of anonymity.
Maybe you enjoy following all the rules set at all levels of your life, but not everyone is so content with their existence. If everyone's movements are known all the time, then any opportunity they have to better their situation other than doing exactly what they are told and waiting for a pat on the head is taken from them.
I am afraid of your world, sir.
