The OP has explicitly denied committing the cherry pion fallacy here. I confess, though, that I'm not sure what point the OP is making by observing that grinding the universe to dust would not produce agenty dust. I can see two non-cherry-pion-fallacy-y things they might be saying -- "agency doesn't live at the microlevel, so stop looking at the microlevel for things you need to look further up for" and "agency doesn't live at the microlevel, but it's produced by the microlevel, so let's understand that and build up from there" -- but I don't see how to fit either of them into what comes before and after what the OP says about agenty dust. Gram_Stone, would you care to do some inferential-gap bridging?
