To be precise, you should precommit to not trading with entities who threaten punishment--e.g. taking an action that costs them, simply because it also costs you. Unfortunately (or perhaps fortunately, given how we would misuse such an ability), strong precommitments are not available to humans. Our ability to self-modify is vague and bounded. In our organizations and other intelligent tools, we probably should make such precommitments.
