For reference, look at how the societal damage of social networks has been handled: too little, too late. Same goes for RentTech.
But, I don't know the solution. The common computer has become so powerful that we cannot simply rely on inaccessible materials to prevent the danger of overly-powerful tech spreading too fast, as we do with bioweapons or traditional WMDs.
Fight tech with more tech, I suppose.
We want to go back to New York in the 90s? Petty theft everywhere?
With great power comes .... ? Profit?
Of course, you wouldn't encode real-time navigation data, but a small block of identifying text. Either way, though, someone without a copy of the spreading code isn't going to notice it or decode it. Given enough redundancy in both the time and frequency domains, removing it wouldn't be easy either.
