It turns out protesters don't need privacy, either, because of various reasons. Same for women seeking adequate healthcare, I'm sure. Or LGBT people attempting to exist.
Sorry, I am strawmanning a little. Actually, we'll simply have regulations on use. Regulation which will certainly be followed this time by a government with complete disregard for Constitutional rights. Certainly they will never be misused by the police currently stalking their ex-partners with existing surveillance systems despite existing stalking legislation.
I wish the legislation you talked about existed already. I am dismayed by the overwhelming number of people that love being surveilled. Without them, we would have it already.
