Rather than get all angry about "national security", how about we all just stop submitting to this tracking. Turn GPS off. Use adblockers. Don't download stupid little free apps that claim to need your location 24/7. Block/randomize/delete every cookie. The tools are out there.
Second, we are well past the point where we can just inconvenience ourselves into getting our privacy back, unless your advice is “don’t use a cell phone or car” and “don’t go out in public” (in which case it will be trivial to determine your location anyways).
Data brokers are lifting your location from every ad in every app, GPS on or not. You have much less control over this than you think. Further, you will likely be identified via license plate readers (those solar powered towers at Home Depot for example) and even your tires report a unique identifier.
And when they want to make exemptions for themselves, make sure to scare them good so they won't.
