One issue would be that it appears that the same argument can be used to argue for the troublesomeness of cyclic graphs.
Consider a graph that is mostly a tree, but one directed edge points to the root. What is the difference that makes your argument inapplicable to the graph, but applicable to a model of reality that contains a model of the model?
Thanks for trying to find a concrete example! Yet to be honest, I don’t get yours. I don’t see either a model or a world here. It seems that you consider the cyclic graph as a model of the unrolled graph, but there is no agent embedded in a world here.
Either way, I provided an explanation of what I really meant in this comment, which might solve the issue you’re seeing.
