I don’t know how you measure “metric tons of content” but I suspect in general there’s lots of US-available content on IPv4 that the countries like China and India want to access, and not much the other way around. But that should be a perfect playground for an IPv6-only network that has gateways to the IPv4 content; eventually the home-developed content will begin to drive demand elsewhere.
