I think your instinct is well founded but at odds with the massive tech industry pushing the other way. This is the classic imbalance between offense and defense: for something like a building’s location, the defender has to do the right thing every time. You put out that order and most people follow it but over time someone’s going to make a mistake - they’ll forget their LTE AppleWatch counts as a phone, their spouse or kid will leave their phone in the car and Facebook will helpfully share that location belongs to people who like military pages, their cell provider helpfully links their vehicle’s integrated cellular device with the other devices on the account when selling data, etc. It feels like the solution might need to start with a significant data protection law making some of that data collection impossible and all of it requiring notification so someone could at least have the chance to know where they’d be breaking policy.
