How can the version without shadow brains be significantly longer? Even in the worst possible world, it seems like the 2% of non-shadow-brain programs could be encoded by copying their corresponding shadow-brain programs and adding a few lines telling the computer how to garbage-collect shadows using a straightforward pruning algorithm on the causal graph.

by the programs being short enough in the first place that those few lines still doubles the length? By the universe like part not being straightforwardly encoded so that to distinguish anything about it you first need a long AI-like interpreter just to get there?
