Convergence is a pretty well understood phenomenon in evolutionary theory and biology more broadly these days. Anything outside of our biosphere will likely follow the same trends and not just for the biological reasons given, but for the game theoretical ones too.
Acausal trade seems unrelated since what I’m talking about is not a matter of predicting what some party might want/need in a narrow sense, but rather the broad sense that it is preferable to cooperate when direct contact is made. As a tangent, acausal trade is named poorly, since there is a clear causal chain involved. I wish they called it remote reasoning or distant games or something else.
