I think this is suggesting that all AI models have restrictions. Yes, some people will ignore those restrictions, but at least there will be some recourse as there will be actual rules put in place. If a company or an individual does something reckless with AI that affects another company or individual negatively the offender may be able to currently say "it wasn't me it was the AI/I didn't know". They may not have technically broken any rules since the current law is not able to account for AI agents acting somewhat autonomously. If there are rules in place then at least we can point to that and say "it doesn't matter that you did not explicitly instruct it to do X, you should have had the following things in place to prevent that".
The fact that some people may be able to run local models and may never be caught does not mean that we shouldn't have the infrastructure in place to stop the harm where and when we can.
