>They can still beat you with a wrench to divulge your information even if it’s on Matrix or even pen and paper.
this does not scale as easily. sure if you are an actual target, your goose is probably cooked anyway but what about the masses? i am just saying, what we call "mass surveilance" and wrench beating dont go hand in hand. mobile number helps them in mass surveilance which can give them more leads.
if that limb is removed, they can still do it but it is a bit harder so the hope is they will focus their time on only serious cases as opposed to everyone willy nilly because it is just so easy
