Note that if Visa/MasterCars were to force two-factor (or 3DS how they call it) the cardster business would be severely hampered, as one could not simply copy dumb credit card numbers around.
But they do not so, because the fraud cost is paid by merchants (fines, fraud buffer in fee %) and ultimately the consumers as higher prices. Fraud does not hurt Visa/MasterCard bottom line.
