Sure, the above is traditionally true. Yet deep pockets solves some of these issues, and producing a lot of these cameras reduces per unit costs. Material advancements can reduce size and other issues too. But think not just now, but soon. And unless the argument is "we can never do this as tech improves", deep pockets and time makes all possible. So the question remains "what if", not "attempt to prove this is impossible currently". What if, once tagged, the movement of all humans outside was tracked, even on foot. Inside has cameras already, dense cities too. It's a capability gap being met.
