Not a very good risk mitigation strategy. A company may wish to hedge 
their bets about the speed of the IPv6 transition.

This seems obvious.

Huh? How could they possibly justify any acquisition of space, no matter 
how small, for this purpose?

Really? A company concerned about future supply doesn't deserve IP 
addresses? The entire point of needs justification is to justify the 
need not just for *today* but for 12 months in the future (or 3 months 
in the future for some unfortunate entities).

This seems obvious to me as well. Leasing is one of the several ways 
holders of IP address space might make it available to others.

This I do agree with.

Can't be that stupid... see and

This is one of the ways that market liquidity is generated. If we don't 
have this then it'll be *harder* to get IP address space when you need 
it, whether or not you can do a needs justification.

This is another reason why the 3-month limits for new/recent entrants 
are such a big problem post-runout... they eliminate speculative 
activity BUT the lack of speculative activity means that coming back for 
more in 3 months is actually harder rather than easier.

Try raising venture capital for a project that will need IPv4 and IPv6 
access once product development is complete and disclose that you're not 
going to try to get space until several months post-runout and see what 
the potential investors say.
