I've always made the mental justification that Gold Leaf can't be planted elsewhere because it functions by channeling the faith of the ancient sun worshipers in order to create a new tile. Without that history in the area, it just can't function, and thus, we are blocked from taking it to other worlds where the sun worshipers had not made their mark on history.
