I can supply the actual text of the ban saying it
ubiq: I’m willing to guarantee any dollar amount (or anything else) of your choosing that you most certainly do not have the actual text of the ban.
I don’t understand what you are saying. At one point hakacha allowed two wives. Then it didn’t.
Incorrect. Halacha still allows it. Non-Ashkenazim still do it ad hayom hazeh. Even Ashkenazim can do it with a heter meah. It is a takana for Ashkenazim not to do it; it is not halacha. You cannot dismiss the differences between a halacha and a takana.
