PAA: So you admit that you’re just putting words into a posek’s mouth: “he said it by one mechanism for igun-prevention, so it must apply to a different mechanism as well.” Unconvincing.
Joseph: I didn’t call it “extra mezonos” (maybe the RCA did but that’s irrelevant). Any husband can agree to give his wife whatever he wants, at any time. It doesn’t matter that the effect of that is to make him more likely to divorce her to get out of paying it. Because if you say that, then the whole kesuba is one giant get-meuseh generator, because he has to pay mezonos until they’re divorced!
