Yep, sure is. Maybe the lack of uniqueness in IPv4 will be sufficient to drive IPv6. But "might handy" isn't "absolute, fundamental requirement".
I think you're missing my point. There are entire continents of people behind single or double NATv4 and they are able to function and communicate. It may not be optimal, but it is workable, particularly for a limited set of applications and services. If we want people to invest in IPv6, we need to explain to them why it will benefit them in terms they understand. There is a billion people's worth of inertia here, so I'm somewhat skeptical that "because you get unique addresses" has sufficient energy to get significant forward motion.
