The “expectation of privacy” is a lie. It’s a misleading way to state what should be the question. It leads one to think, “heck, that’d be silly, to expect privacy in public”
It also makes it an issue of what we expect, rather than what we have a right to, or what we would like to have a right to.
As this is supposedly a democracy, I’d prefer to be asked, “Would you like to have a right to not be identified, tracked and recorded everywhere you go unless it is your own privately-owned property?” The answer is yes, I would.
Privacy is one thing. Being watched, photographed, recorded, having my movements and transactions put into a database for later possible (ab)use, is, in my opinion, horrible, stifling, and evil. And should not be allowed in a country that says it has a constitution that allows me life, liberty, and the pursuit of happiness. It sucks some of my will to live to be monitored and tracked, it substantially impairs my liberty, and it sure as heck makes me unhappy, having been made to sing songs about the “land of liberty” when I was a kid.
Oh, so what do I have to hide? Only my utter contempt for my nation’s backslide into corruption, cowardice, world domination, police state bullshit, etc.
