Sure, but that's telcos and the local law enforcement. It's not google, facebook, 500 advertising networks and a whole pile of other parties.

It's also not accurate to within enough resolution start targeting advertising and other nuisance information at me even if there was a way to present me that (which there isn't).

I'm well aware of the power of triangulation, I used to go fox hunting.

In some places, "just telcos" doesn't mean much: http://www.latimes.com/business/la-fi-lazarus-20140425-colum...

Though European laws are still mostly sane in that regard.
