This seems to be the unproven assumption and flaw in the IPv6 logic.  
Rationing doesn't "stretch" the lifetime of IPv4, and doesn't delay the 
move to IPv6.  IPv4 will continue after exhaustion of the Available 
pool.  Address space will be returned or reclaimed, and allocations will 
eventually resume.  Exhaustion in this case just creates a bump in IPv4 
operations.  That bump, and consequences of the bump, can be avoided. 

However, there is no case where that bump greatly improves the
transistion to IPv6.

Just the opposite.  Your scheme seems to be desperate and makes me 
more suspicious of IPv6.  If IPv6 could stand on its own merits, you 
wouldn't need to try to wreck IPv4 to promote it.

However, your attempt at wrecking IPv4 will fail, because IPv4 will
survive, albeit with disruption and other more nasty problems that are
entirely avoidable.  This is just an irresponsible attempt at
destruction, by people trying to promote IPv4.

I'm going to have to look into IPv6, to find out what's wrong with it,
that you would need to disrupt Ipv4.

Well, this happens with or without rationing.

????  You can try again and again now, too.

???? No difference whether rationing or not. 

None of your arguments make any difference under rationing or not 
rationing. So, they don't have any relevance to rationing.
