You are welcome. Sometimes, as with ANY parent, kal v’chomer with haKadosh Poruch Hu, we must do things just because they said so. We have many mitzvos that are chukim, that fit that category. Parah Adumah, Shiluach Hakan, are but two that come to mind.
BTW, it actually was a rov who told me what I had posted about the shaitel or head covering being for the benefit of reminding the woman herself of her married status, because it is a permanent physical change that she must accept upon herself.
