You really think so? Even for IPv6?
For me the real value is that RIRs provide uniqueness, that is their 
true value. Just like a cadaster. Conservation has been an additional 
task that has been put on the RIRs thanks to the limitations of IPv4 
(<mild sarcasm> and surely IPv6 will solve that </mild sarcasm>.
Was the main goal of the RIPE NCC conservation (other than through 
promotion of CIDR) when it came into existence?

However that affects one at a time, rather than all at once. I mean if 
go shooting ducks I really prefer to have them all nicely bunched 
together so that it requires less skill, but if I am a duck I would 
rather make it more difficult for the hunter (or wild sniper entering 
the burger shop, as it may be)
