HaKatan: I don’t usually engage in a dilaogue with you- we will never agree and I find your incessant comments on Zionism ultimately boring. However, as you mentioend Poskim and the gemoro end of kesubos,I might as well respond.
It is certainly not halacha and therefore any Possek cannot find solace in his Piskei halocho based on this gemoro. You will have to find me a Rambam or a Se’if in shulchan aruch that refers to this gemoro as halocho.
