It compels requesters to consider deployment at least as far as
completing the paperwork.  They may go ahead and "just do it" once they
realize the most basic requirements are met and they have the resource
already literally in their hands.  Or they won't.  It really doesn't
matter.

What does matter is that they'll have it for the day when it becomes in
their interest to do so on short order.  How many more participants in
IPv6 day do you think there would have been if address blocks were just
laying around waiting to be deployed by excited network engineers?

Please substitute the term IPv4 for IPv6 in the above and re-read.
Done?  Good.  An organization who can justify an IPv4 allocation from
ARIN is surely in the same position to justify an IPv6 allocation from
ARIN for the same network.

If this did not work for the homogeneous and hierarchical US Department
of Defense, it surely will not work for the heterogeneous rest of us.

Why not?  It's widely deployed and proven effective.  Further, it fits
perfectly with the concepts of end-to-end connectivity, the role of
routing infrastructure, and is easily understood: "Ohh, so the entire
IPv4 internet fits into this nice little 2002:: chunk and I get all
these addresses mapped for free?  Got it.  And my hardware and software
already do this?  Cool.  How do I turn it on?"

Are you're seriously advocating NAT444?  Allow me to condense the long
investigation into why this is bonkers by generalizing the wrongness
into one very simple statement:

Nothing -- and I mean nothing -- along the path should be molesting my
packet in any way whatsoever.

As corollaries: You do not steal bits from a field of a deeper layer in
order to pretend that you have a larger network address space.  You do
not handle routing by introducing stateful information from outside the
network layer.

And as a frank aside, how is it that I can hear a carrier whine about
how the BGP table is getting unmanageably large while at the same time
hearing him advocating for what amounts to introducing and consistently
tracking a thousand little state entries per /32?  Yeah, I know the
difference between core and border.  But there's obviously a serious
mental disconnect here.

Well, then don't phrase it as deprecation.  ARIN seems to have no
problem regularly proclaiming IPv4 address exhaustion.  How about
sunsetting the handling of requests for any actions related to IPv4
allocations?  "What's out there is what's out there.  We're washing our
hands of it."

Is it?  The IETF is an standards body.  ARIN is an operating body.  You
probably meant IANA.  And speaking of saying, "What's out there is
what's out there.  We're washing our hands of it."  The only way they'll
probably get involved in IPv4 again is if through some seemingly
impossible turn of events one of the RIRs relinquishes a /8 for one of
the others to fight over.

If ARIN is still primarily screwing around with IPv4 in 2019, perhaps
this is indeed the most appropriate course of events.

Sigh.

Actually, no, the market is what caused the success of TCP/IP.  Dig up
someone (sadly, this may require a literal interpretation) from Novell,
DEC, or Apple and ask about how that all happened.

Yes, I understand that it's easier to generate and disappear into the
smoke and miasma settled over the field of economics.  But you'll notice
that I have not yet made even one suggestion economically rooted.  So,
what do you say that we just leave economics as the aside it was
intended to be.
