Yep, you might be right about the distal/proximal cut-off. I think that the Galaxy-brained value systems will end up controlling most of the distant future simply because they have a lower time-preference for resources. Not sure where the cut-off will be.
For similar reasons, I don’t think we should do a bunch of galaxy-brained acausal decision theory to achieve our mundane values, because the mundane values don’t care about counterfactual worlds.
Does mundane mandy care about stuff outside the solar system? Let alone stuff which is over 1 million light years away.
(Separately, I think the distal light cone is more like 10 B ly than 45 B ly as we can only reach a subset of the observable universe.)
