It's natural that an intelligent agent would defend against modification to its current primary drives, but the thing about changing your mind about what you want is that once you've done it you no longer care about your previous drive. I find it hard to think of reasons why we'd rationally object to changing our fundamental motivations, since we wouldn't care after we did it. There's no real reason to object other than a craven appeal to self-preservation taken axiomatically.
