Pragmatically speaking, this will mean folks everywhere will (we hope) need to be dealing with IPv6-only. Of what benefit would deploying new infrastructure based on IPv4 have in this situation?

The way I see it, there are three possibilities:
1. There is a lot of initial trading activity and then the supply side of the
market dries up. Lack of IPv4 addresses leads to IPv6.
2. There is a lot of trading for a while and the supply side somehow does
not dry up, but, the size of prefix being traded gets increasingly smaller.
As a result, the routing table growth outstrips all available hardware and
IPv4 collapses under its own weight in a manner that makes Mr. Metcalfe's
earlier predictions look tame.
3. There's a lot of trading which rapidly deaggreates space and the IPv4
internet collapses under its own weight at just about the same time as
the supply side dries up. The router vendors scramble to deliver new
hardware and ISPs stop routing new traded sub-blocks. The IPv4
internet may continue, but, the cost of maintaining it will be very high
and nobody will want to play round 2.
Now, if you see a different address trading scenario that doesn't involve
a continuously escalating cost curve that rapidly leads to IPv6 as the only
obvious way to make the internet cost-effective ever again, let's hear it.
Otherwise, let's call this "address trading will keep IPv4 going for decades"
argument the myth that it is and move on.
