I think full agent-neutrality/multisets will make it basically impossible for anything to matter in practice assuming the universe is infinite (maybe you can only care about finite universes, though). You’d need to change the number of individuals at some utility level to make any difference, but if the universe is infinite, the number of individuals at any given utility level is probably infinite, and you probably won’t be able to change its cardinality predictably through normal acts that don’t predictably affect weird possibilities of jumping between different infinite cardinals.
If a hyperreal approach gets past this, then it probably assumes additional structure, effectively an order.
