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.
