No problem. You can only have a preference that doesn’t get traded off with if it happens to never conflict with anything—for instance, my preference that there be a moon has yet to interact with any other preferences I could act towards fulfilling; the moon just goes on being regardless—or, if it’s your only preference. Even if you have only one preference, there could be tradeoffs about instrumental subgoals. You might have to decide between a 50% chance of ten units of preference-fulfillment and a guarantee of five units, even if you’d really like to have both at once, even if the units are the only thing you care about.
