I think that acausal trade is a valid way of causing things to happen (I could have phrased that differently, but it is causation in the Pearlian sense). I think that this is somewhat value-dependent, so a general agent in reflective equilibrium need not care about acausal effects of its actions, but I think that, if it makes any sense to speak of a unique or near-unique reflective equilibrium for humans, it is very likely that almost all humans would agree with acausal trade in their reflective equilibria.
You… think it is impossible to understand acausal trade without agreeing with it?
