GAW, nobody said that CH”V the Ramban is not valid. The question is if/how applicable this mitzva is today.
As I wrote, Rav Moshe said it’s not applicable to Jews outside E”Y.
benignuman, point taken. But denying any part of the Torah is kefirah, even if your excuse is wanting to fulfill Yishuv HaAretz beyond its halachic bounds.
