If there would be enough unpaired devices in the wild, both types of devices would get stolen (or, worse, robbed, with risk of bodily harm). Thieves would not return the ones that are worthless to them to their owners (why would they take that risk?). So, it would make the protection worthless for those willing to opt-in. And no, making it somewhat easy to check whether a phone is locked down wouldn’t help. Thieves and robbers won’t spend even a second to do that check while still near the crime scene. It would have to be absolutely obvious (say by having orange and black devices) for thieves to not steal the locked-down ones.
