I think a lot of people think the fears are overblown, that government is basically perpetually inept but well-intentioned, and even if they do capture everyone's data, they can't possibly make sense out of all of it or connect all the dots on each of us meaningfully & use that to impinge on our liberties.

I, of course, think that's dangerous and short-sighted thinking and there are higher principles at stake here (and for the future), but I get a strong inkling a lot of folks shrug and feel this way. My wife, for instance.
