DaasYochid; you are certainly referring to another thread snd my comments about the shulchan aruch.
Indeed, especially since R’ Yosef Karo disagrees with the Ramba”m you refer to.
It’s fair to assume that he (as well as all who disagreed with that Ramba”m) are aware of the concept of kesubah. I’ll leave you to figure out why using the kesubah in this context is utter folly.
