How the identity number would help? It's not like terrorists tell each other their identity numbers. So if the LEOs learn about a terrorist guy that goes around under the name "Sean Byrne", how would they know which ID number that is? And even if I needed some ID number to put on my fake documents, it's easy to download one of the dozens data dumps on the darknet now, and just use any of the IDs there. The LEOs then have a choice - put that number into their ban database (therefore banning some innocent person whose only fault is that he made a mistake of participating in the economy) or go just by the name (which is not better). Don't see how it changed anything.
