Sam2-
I agree.
However, the statement is very ambiguous.
In regards to what is it d’rabbanan?
In regards to speaking ????? ??????? why would you say it’s d’rabbanan? Even if it’s an ?????? and ???? in societal norms, at any rate, if in a particular society it is something which can be called “ervah,” then the pasuk of ??? ???? ?? ???? ??? applies. Which would make it d’oraisa, unless you tell me that drasha is an ??????, but you would have to show your basis for saying that. And if in a particular society it is not called “ervah,” then it would be mutar, as the Aruch Hashulchan paskened and numerous other poskim.
In regards to covering it, I have already noted here and on a lot of other threads that I don’t believe this halacha primarily has anything to do with ??? ???? ????.
To everyone saying there is a problem with attractive sheitels: Please see my first post.
