Except it doesn't work like that in practice. It would be nice if it did. Often a person can be found guilty simply by jury in a trial based on what they think a person might have done. That's reality, and it is the case in western would countries not some obscure dictatorship.
The solution to not being poor is being rich. You could apply that logic to a lot of things. Have this thing instead of that thing. Using your example above of "differential privacy scanning"
Differential privacy is a property of a dataset meaning you can’t tell an individual was part of a dataset. If it’s traceable back to the individual device it’s not differentially private.
I think at this point you're just trying to say "don't have this thing have that thing instead" as a response to anything.
