Couple of things here - what do you do with the open source models already published? There’s terabytes of data encapsulated in those. Some have published corpora, some don’t. How do you plan to determine that a work comes from an unregistered AI?
Also, with respect to “within the country” - VPNs exist. TOR exists. SD cards exist. What’s your plan to control the flow of trained models without violating civil rights?
