 If this is right, then it is one important motivation for denying that “good” can be understood in terms of “better”. But it is important to be careful about this kind of argument. Suppose, for example, that, as is commonly held about “tall”, the relevant comparison class or standard for “good” is somehow supplied by the context of utterance. Then to know whether “that is good” is true, you do need to know more than all of the facts about what is better than what — you also need to know something about the comparison class or standard that is supplied by the context of utterance. The assumption that “good” is context-dependent in this way may therefore itself be just the kind of thing to explain the intuition which drives the preceding argument.
