In reality, we're already past runout and we have been for years if you define runout as the point at which genuine needs cannot be fully and rationally satisfied. We passed runout as far as I'm concerned at the point where we were no longer able to take every host that is currently behind NAT and put a public address on it instead.

So, instead we find new and different ways to lie to ourselves and pretend that the free pool today is not measured in the pain of others and that we can magically extend the life of that free pool, conveniently ignoring the pain such actions inflict.

In theory, there is no difference between theory and practice and we 
have run out.

In practice, there is, and the evident fact is that there is still 
plenty to go around.

Hence, this discussion.

There could be quite more kept available, if the theorist did not keep 
stonewalling practical attempts at doing so.

What theory glosses over is that need is relative, and elastic.

Actual practical use of IPv4 has demonstrated that over and again.

Your theory actually cites two conclusions that are actually measurable. 
Bad Theory!

Did you miss the part that actual address consumption has changed?

Has anybody noticed increased route table growth driven by increased 
rate of ARIN smaller sized allocations? Which would not happen all by 
itself, or spurred by market activity growth?

Or are those the inconvenient facts that does not line up with your 

I feel really bad for these organizations who have more addresses then 
everybody else combined and yet manage to charge 15USD for a block of 5 

Where are they getting those addresses to do that with? They must need 
more. Give them a 12 month supply..
