From a privacy standpoint, I’m hard-pressed to see what the concern or objection could be

Really?! You're looking inside my fucking car! Without a warrant! That's what the objection is. Do these people hear themselves speak? First you put cameras everywhere I exist, then I go through your metal detector, get patted down, submit to a body scan, have my conversations recorded (sometimes), my cell sends all my keystrokes, Facebook advertises my phone number, bots crawl to get my email, and I'm basically reachable 24/7 even if I turn my electronics off. Then you roll out the roving x-ray machines on wheels and tell me I shouldn't object? Nuh uh. Enough's enough. I basically have to live in a cave to avoid being tracked but even caves barely cut it these days.

Living in the US you get used to having no privacy and for the most part I've never really cared. I always figured that if you're doing nothing wrong there's no problem. But then I notice that every time I shrug something like this off they come out with something just tad more invasive. Maybe this is my personal epiphany, the point where I turn and say "hey, this stuff isn't cool anymore". I now see that if you give an inch they take a mile. I'm switching sides. I'm on the privacy nut side now.
