I don’t feel I heard a good reasoning why a kehila shouldn’t return to a minhag that was coercively banished by a government gezeira once the gezeira is abolished. But be that as it may, I’ll put that question aside for the moment.
Am I correctly understanding from the sources offered here that the Mechaber opposed sheitels but the Rema permitted them? Thus they’re okay for Ashkenazic kehilos that accept them but not for Sephardim? And that the sources cited in this thread permitting are from the Ashkenazic world.
One point I’m unclear about is that it was mentioned here that the Gemorah permitted sheitels. If that is so, why was there the subsequent strong debates for many centuries among the latter poskim pro and con regarding peah nochris, if the Gemorah already paskened this matter.
