If I have a computer made only of naturally occurring atomic elements, and I use it to simulate a plutonium nucleus, are you saying I now actually have a plutonium nucleus there?
“Actually have” is vague and should probably be tabooed. Yes, in that there is a causal structure there isomorphic to a plutonium nucleus; no, in that this causal structure has the wrong relationship to you.
