The "deck chairs" analogy is becoming a go-to for anything that
mentions IPv4 these days. The problem as I see it is that there are
still some members of the community who have not come to the same
realization that you and I have (IPv4 is dead, IPv6 is table stakes).

So... What happens if a few large/important enough organizations are
able to spend the money required to buy the rights to IPv4 addresses
(or companies which possess the rights to IPv4 addresses) in large
enough quantities to defer their own IPv6 deployment long enough to
make others reconsider their own transition strategy (and the expense
of implementing it)? I don't believe that they could ever kill IPv6
long term but they may very well be able to deepen and prolong
everyone else's transition pain.

The bottom line at this point is that deploying new IPv4 addresses
(beyond those you already have in reserve) without also deploying IPv6
is at this point a waste of those IPv4 addresses and has the potential
to harm the other members of this community. Justified need policy has
ALWAYS had a 'you must deploy your network the way we say' attitude,
it says that you are not allowed to deploy your network in a way that
wastes IP addresses. This policy proposal simply updates what it means
to waste addresses.

Stewardship does not always allow one to look the other way,
especially when someone else's short-sightedness will harm the greater
