Dude, come on. You do understand. The feature is like a fence in a yard. It separates the honest from the dishonest, forcing the clueless/negligent/reckless to pick a side.
Nobody believes fences stop criminals, and nobody believes Gmail has ended the DRM arms race.
I agree with the thrust of your comment, but this isnt true. Measures like this do prevent some crime. When i didnt lock my car and someone stole the gift cards out of it, locking the doors would have prevented it. Just because the car is still stealable doesnt mean door locks are security theater. Putting an unlocked package cabinet for deliveries on your porch lowers incidences of theft without making it impossible.
