I’d be willing to bet they would take privacy protections a bit more seriously.

Or at the very least they'd think twice before grandstanding against the construction of a strip club or whatever when anyone can look back and see their patronage of such.

It would change how much surveillance there was in the first place.

1 - you don't actually have access to that information.

2 - you're lowballing the problem. It's not just current location, it's your full movement history.

Oh no no no, those are private for security reasons!
