A lot of orgs will NOT even look at IPv6 until that crash happens.

That's just human nature.

Correct.  I don't subscribe to the excuse that anyone is ever going
to be able to say "We don't have IPv4 connectivity" with a straight
face.  There will ALWAYS BE an upstream they can get non-portable
numbers from.  And if IPv4 is that scarce then there would be good
money to be made for IPv4 holders to sell (or offer for free)
IPv4 via tunnel, just like Hurricaine Electric is doing with IPv6
