Yes, assuming that trading across possible worlds can be done in the first place. One thing that concerns me is the combinatorial explosion of potential trading partners. How do they manage to “find” each other?
It’s the same combinatorial explosion as with the future possible worlds. Even though you can’t locate individual valuable future outcomes (through certain instrumental sequences of exact events), you can still make decisions about your actions leading to certain consequences “in bulk”, and I expect the trade between possible worlds can be described similarly (after all, it does work on exactly the same decision-making algorithm). Thus, you usually won’t know who are you trading with, exactly, but on the net estimate that your actions are in the right direction.
I currently agree it’s a bad analogy and I no longer endorse the position that global acausal trade is probably feasible, although its theoretical possibility seems to be a stable conclusion.

Isn’t the set of future worlds with high measure a lot smaller?
