Whatever people try to imagine that science supposedly can't analyze, it just ends up as more "stuff that makes stuff happen and happens because of other stuff".

I think said people would object to this - e.g. "God certainly isn't stuff, God is metaphysical!" This, of course, is not problem for causal diagrams. The math allows you to have arrows from metaphysical stuff to physical stuff, which allows you to see occam's razor visually. But it's interesting to think about how to best counter this argument when you're trying to convince your opponent and not just yourself.
