No I think Kant’s “ought implies can” principle usually uses “can” to mean some kind of “practical possibility” that means “possible given your powers and opportunities” or something. And whatever is possible in that sense is also physically possible (i.e. “possible given the actual state of the world and physical laws”). So the argument is still sound.
