Yes, I hear you. It would then come down to what's easier to do correctly, authenticate an EMV transaction or read and validate the fingerprint of a card's mag stripe. To the best of my knowledge, I don't think anyone has been able to replicate a mag stripe's fingerprint on another card's mag stripe. However, this security measure has probably seen a few orders of magnitude less adversaries than EMV and RFID have.
