ata’s reply was that “we disagree” additionally indicates that we can potentially converge on a common answer by arguing
That doesn’t seem to be what the dictionary says “disagreement” means.
Maybe if both sides realise that the argument is pointless, they would not waste their time—but what if they don’t know what will happen? - or what if their disagreement is intended to sway not their debating partner, but a watching audience?
I agree with you about what the dictionary says, and that people might not know whether they can converge on a common answer, and that people might go through the motions of a disagreement for the benefit of observers.
