Most intelligent beings in the multiverse share similar preferences, because the process by which they were created / come to exist share major parts / have similar constrains / it’s a logical fact that some preferences are more likely to arise. So it’s not a fact about the logical structure of “having preferences, being and agent” thing, but of “coming to exist in the multiverse” thing. And if you discover what kinds of preferences are likely you can invert it without major obstacles and create an atypical agent, but you yourself is an agent who wouldn’t want to do that, most likely.
I would also add:

Kind of like #2? But I’m not sure.
