Yes, but I'm forcing a tautology in my logic - if in the end it is deemed the only way to stop AI from destroying the world is something that helps Anthropic or OpenAI - then this person is asking to not perform that action.

And unfortunately my tautology is actually closer to being reality than alternatives. Stopping progress even in Chinese models (a deal with Xi for example) but that specifically helps OpenAI/Anthropic.

There are very few scenarios that would not help these two companies by adding regulation. Your counterexample is 100% less likely because it's not legal for the US to nationalize them outright without taking other action first.
