The issue that I and many other people on the ARIN AC continue to come back 
to is that this sounds a lot like the logic that was used when deciding how 
to originally allocate IPv4 address space.

The fact that people have figured out how to conserve IPv4 address space 
(dynamic addressing, HTTP/1.1 Host: headers, etc) is a tribute to the fact 
that it _can_ be done if need be.  But that's just the point, it was only 
done out of _necessity_, not because it was the right thing to do.  The 
concern is that if we go back to an attitude of 'we will never run out of 
addresses' then we will find ourselves in a very unfortunate situation once 
again.

Memory can be very short.  We must learn from history, or we will be doomed 
to repeat it.
