>But does it actually matter?

Probably not, because most of us are boring. Most of us don't have stalkers. Most of us don't have government clearances. Most of us aren't politically adjacent, significant, or know someone who is. Most of us are not wealthy. Most of us will not be a target by the relatively small pool of humans who could actually do anything with that data.

I might have a few chains where I do connect to someone important (degrees of connection to Kevin Bacon), but that isn't directly useful here.

The point is it's still private information and it must be protected, if only out of common sense or respect for your fellow humans. We don't need damages to defend this point.
