That argument is defunct. That is why I ask again; what do women prophets, caliphs, and Imams have to do with what we are discussing? No one else mentioned women prophets, caliphs, and/or imams. If you retrace your steps, you'll realize that you have been arguing everything from "women can't govern" to "women can't fight in wars" to "Hazrat Ayesha never lead anyone during the battle of camel", that too by claiming that these are decrees "by Allah himself".
Just to clarify, I know what you are trying to contend but I need you to explicitly state it so that I can show you how and why it is incorrect.
