I would say that only non-physical system implement counterfactuals.
That counterfactuality is the essence of (immaterial) comp. Although
here Russell has a point: the quantum multiverse seems to handle
counterfactual. Now if comp is correct, I cannot distinguish a
"genuine" quantum multiverse from any of its emulation in Platonia, and
the physical laws must take that into account.
