You cannot ban this technology, because you can't enforce it. It's essentially similar to Napster. If you ban it, 30 more popped up. It wasn't until streaming made the $15 + convenience a better value than free media + viruses that piracy fell out of the mainstream.

I think the best solution currently is to require videos to label such content, such as how sponsored content must be labeled. Granted, this only works for now while deepfake technology is still detectable.
