Look around you. See all those cameras? Not just the ones above your head in the supermarket that advertise HERE I AM, I'M A CAMERA, but every camera on every phone in the hands of every person you see can identify you and identify your exact location to the meter instantly based on your face and x other biometrics.
Everytime you speak, your voice pattern identifies you instantly.
Burner phones are a thing of the distant past. The moment you speak, the moment the camera "sees" you, your burner phone's IMEI is/can be mapped to your identity in double time.
The methods in use today are just way more sophisticated than the tech you've read about.
A drone at 20,000 feet can identify you in a crowd of 2,000 people based on the sound of your heart, your respiration, the shape of your head, your ears, your nose, your face, your facial profile, the shadow your body casts at x time of day, and/or the uniqueness of your gate. Combine them altogether with a scant amount of stat analysis and you can't hide even with effort.
Means absolutely nothing if license plate tracking, biometric (facial et al) tracking, financial tracking, and other more sophisticated forms tracking, from link tracking (follow your social grouping = easily follow you) to drones and beyond.
We'll get none of it as long as vested interests strenuously and financially (read: lobbying/PAC-political donations) object to the very construct of an implicit right to privacy, and the possibility of an explicit right that, say, adds superpowers to 4th Amendment is so far off that one sees the fall of humanity on the horizon long before any such thing is put to bill.
