Such statistics would be very useful to society. Tracking people as a group to figure out how they behave. Its only when the tracking targets individuals that it get creepy.

"New York'ers goes to the toilet x times a day" is fine vs "John Doe goes to the toilet x times a day" is not.

I'm not arguing that they aren't useful---they are, and quite fascinating.

But they should always be opt-in.
