If you’ll notice, he explicitly uses the phrase “unobservable components of the universe’s wavefunction”, and the context is clearly many worlds quantum mechanics. This means your thought experiment is not at all analogous to his statement.
Your implied invisible (observer outside the light cone) is qualitatively very different then his implied invisible (unobservable components of the wavefunction). Your thought experiment shifts the focus by subtly redefining the original statement.
I’m actually with wedrifid here. I think the key point where wedrifid and I disagree is that I don’t believe agents benefit from considering any kind of acausal trade or interaction. And it turns out that if you restrict yourself to physically interacting agents, you don’t have to worry about unobservables. In contrast, if you worry about acausal interactions, it can make sense to worry about them.
