And as prices rise we can expect a gray market of IPv4 blocks much worse
than what we see today.

Agree. However, this has an unfortunate side effect: Since money will
differentiate the haves from the haves-not, it is a reasonable
assumption that large organizations such as multinational corporations
and developed countries will actually never run out of IPv4 addresses
because they are and possibly will remain in the top tier that can
afford them.

Why is this unfortunate? Because these large organizations can indeed
delay IPv6 deployment until the last minute.

Which unfortunately will likely be delayed for the reasons I mentioned

I concur.
