That would appear to be what people are arguing for, yes.

Not really.  The fact that PI /48s are available does not  
automatically mean everyone must obtain them.

Two points:

a) huh?  Last I checked, there were 800 IPv6 prefixes being routed
b) I have been told that folks from both Juniper and Cisco have  
stated publicly that they can easily meet short term routing  
requirements and have no concerns about meeting longer term

In the immortal words of Dr. Peter Venkman, "Human sacrifice, dogs  
and cats living together - mass hysteria."

Even if the RIRs started paying people to take IPv6 prefixes, you  
wouldn't see a jump "jump by at least one order of magnitude  
overnight, perhaps closer to two orders of magnitude."  The fact that  
someone has address space does not mean ISPs must route it.

And, as I understand the discussions, that's sort of the point.   
Since around 1994 or so, the RIRs have been tagged with being the  
routing police.  Now, we're told by router vendors that today,  
routers can handle an order of magnitude more routes than what  
they're currently handling.  As such, the policies created to enable  
RIRs-as-routing-police come into question.

More to the point, the allocations of /19s and /20s (and shorter)  
could be seen as egregious and unconscionable wastes of vast tracts  
of address space.
