kasha-
That is just as speculative an approach as mine. It only isn’t speculative if the actual source of the halacha specifies that reason, which it does not. Therefore aside from the fact that it’s a gezeiras hakasuv, all we have is speculation.
About a woman not being an eid, I can speculate more. But I’m not sure I see the point. All I was trying to say is that you have no proof that a woman has a general obligation to obey her husband, and that I think in general they have an equal say. I never said anything about men and women having the same dinim in kol hatorah kulah, and I don’t think I ever implied that. It seems like your using my opinion here to pin the entire feminist agenda on me and then debate me on points I never made, which is just not fair.
On the other hand, if you’re stam interested in my opinion on other matters, I’ll gladly share it. Let’s just first be clear where we stand.
(Agav, I’m not even so sure your speculation is plausible, because who said the chicken came before the egg? That is, perhaps the kinyan was set up in a way that the man acquires and not the woman specifically because of the reason I gave!)
