[arin-discuss] IPv6 Why as justification for IPv4?

Hello folks,

I don't get this twist on V6 holdings as justification for getting V4 allocations.

We were in a world of V4 which had to transition to something new because V4 (that would never run out, as thought 15 years ago) so 
we came up with V6.

If there are some creative intelligent people who built an infrastructure of all V6, I am amazed. They are Genius with a capital G 
because I am in awe of your doings.

But please tell me why that should be used as a criteria for dispersion of V4 IP numbers.

As more and more Genius providers connect more and more V6 customer base, then the need for V4 should decrease drastically.

I don't see the logic. Is it a reward for making use of V6?  Are we new suddenly rolling in newly unused V4 now because V6 is in 
such widespread use?

Time for an analogy?   If I go into a tavern and can successfully consume.... Well, Nope that analogy goes nowhere.

The summary of my thought pattern is straight forward.  If you need or want V6, you requisition for V6. If you need or want V4, you 
requisition for V4.

In the end, I was to believe a strive for a transition over to V6 with backward compatibility for the tiny quantity of V4 still in
