There’s no Darwinian selective pressure to favor agents who engage in acausal trades.
I think I would make this more specific- there’s no external pressure from that other universe, sort of by definition. So for acausal trade to still work you’re left only with internal pressure.
The question becomes, “Do one’s own thoughts provide this pressure in a usefully predictable way?”
Presumably it would be have to happen necessarily, or be optimized away. Perhaps as a natural side effect of having intelligence as all, for example. Which I think would be similar in argument as, “Do natural categories exist?”
