mitzvot lav le'henot nitnu (IV) - kilayim b'tzitzis
R' Shimon Shkop asks a beautiful kashe worth savoring over Shabbos. The issur of kelayim is to have hana'ah from wearing clothing of wool and linen. R’ Shimon asks: According to the Rashba, mitzvot lav le’henot nitnu teaches us that even when there is physical hana’ah associated with a mitzvah, we look at the act purely as a ma'aseh mitzvah and discount completely the hana'ah. If one is wearing a garment of kilayim for the sake of the mitzvah of tzitzis, based on the Rashba's understanding, the hana'ah derived from wearing the garment is not considered hana'ah; therefore, one is not in violation of the issur kilayim. If so, why do we need a pasuk to teach us that one is permitted to wear tzitzis made from kilayim based on aseh doche lo ta'aseh - since mllh"n, there is no hana'ah here and no violation of the lo ta'aseh!?
