The point is to make it harder for “those people” to vote and participate in society. If you came up with a magical, iron-clad, mechanism for everyone to have ID, the conservatives wouldn’t support it because that’s not what they want. They want minorities to suffer.
I’m pretty sure that simply putting a picture of eyes in the scene reduces theft. People are emotional creatures , and if they feel like they’re being watched by someone who doesn’t approve of stealing, they’re more likely to refrain.
