It's very possible to enforce when you realize most AI stems from a very select bunch of platforms, and even "rogue" AI makers rely on these choke points. In the current stage, enforcing a ban against current AI tools would be quite devastating.

For clarity, I'm not in favor of banning, just that we're still a very long way away from the genie being out of the bottle here. Maybe within the next 5 years if pace keeps up.
