There are too many civilizations in the multiverse to simulate all of them. We can only do a sampling and then decide how to trade based on the statistical properties, but this gives an incentive to free-ride (i.e. getting the benefits of trade from other civilizations that did not specifically simulate us, without paying the costs), which may cause an overall breakdown in trade.
Hmm, but if each civ simulates 1 million others, every civ should be simulated 1 million times? I.e. the more civs in the universe, the more civs to do the simulating. And then i think there’s a stable equ where you only give nice things to the civs you simulate if you see them giving nice things to the ones they simulate. I suppose there’s a q of whether we’re able to achieve that equ?
Also, you can do the thing where when your sims run their own sims, you insert your universe into their sim, guaranteeing 2-way trade?
