The only difference between routed and unrouted (note the difference between that and routable) is consensus. There is nothing inherent in the bits which prevents RFC1918 from being routed globally. There is no requirement to use RFC1918 for NAT. Therefore, your argument doesn't hold water. If the entity for some stupid reason can't use RFC1918, they can and should use their _own_ address space for the balance.
