Only if we let it be. There's no technical reason why the origin of a video couldn't have a signature generated by the capture device, or legally requiring AI models to do the same for any content they generate. Anything without an origin sticker is assumed to be garbage by default. Obviously there would need to be some way to make captures either anonymous or not at the user's choice, and nation states can evade these things with sufficient effort like they always do, but we could cut a lot of slop out by doing some simple stuff like that.
