The linked article describes a tracking system that would be mandatory for every single American in order to e.g. board public transportation. (Such a system has already been rolled out in China where people get an automatic red–yellow–green health code and have to show it in public places.) While one can reasonably assume that the NSA is already capable of tracking a huge amount of phone location data from Google or Apple devices, people are still free to not have such a phone and they are still able to move around in public.
