You're remembering to include the cost of migrating both sides, for all combinations of sides interested in communicating, right? In some cases, that cost for one of those sides will be quite high.

The interesting question is at what point _can_ you do what you want without IPv4. It seems obvious that that point will be after the IPv4 free pool is exhausted, and as such, allocated-but-not-efficiently-used addresses will likely become worth the effort to reclaim.
