In the vein of principals, yes, privacy for its own sake is valuable to me.
In the vein of practicalities, both Google and the justice system (USA for me) are monstrously large bureaucracies known to make difficult-to-redress errors. Google's capricious account banning, police raiding incorrect addresses, eg. The decision to share with them more information than the law requires is one I'd prefer to make myself.

Or just plain out refusing to fix errors where they would be relatively easy to fix; compare Scalia's "it's fine to fry a provably innocent person as long as the procedures are followed" argument.
And I think this view is irrational. Privacy for its own sake is effectively hoarding, and as you clearly show, hoarding can be caused by fear, which you have for Google and the justice system.
A numerate person would know how rare these things you're afraid of are, and not let those fears drive how they live. I (hopefully) follow that path, and I recommend you check it out!
I read what you wrote in the same way I suspect you would read someone who is afraid of space because meteors have killed people (as a rough example).
It just doesn't seem like the rates at which the things you're worried about are happening in a volume that would actually matter to a society.
