My answer would be a qualified yes.  No matter how good the translation 
mechanism is, it won't satisfy all need for IPv4 addresses during the 
transition.  (For example, translation may work very well for clients, but 
servers probably need a certain number of unique IPv4 addresses.)  In such 
a scenario, new market entrants would still need their own IPv4 addresses 
in order to provide Internet service to content providers.  Without a 
transfer policy, such new ISPs would have to settle for PA space (from an 
ISP or from some legacy holder who gets into the IP-renting business). 
That wouldn't be the end of the world, but it would be a good deal 
messier, IMO, than a straight transfer of space.
