When the IPv4 free pool is exhausted, I have a sneaking suspicion you'll quickly find that reclaiming pretty much any IPv4 space will quickly become worth the effort. Extrapolations of current IPv4 address space consumption become precisely useless when the existing policy regimes no longer apply. This is not to say folks shouldn't be aggressively pursuing IPv6 deployment, merely that there is a vast installed base that will continue to require IPv4 addresses even after the RIRs allocate the last block they control.
