Impossible to know - it is equally possible to cause parties to avoid 
IPv6 on the assumption that such large networks are not migrating...

Future sales contracts are not a mechanism that would occur in policy, 
so they are not directly addressed by the paper.  

> Both "conservation" and "excluding speculators" are modified significantly in their meaning if we have big players locking up exclusive access to /8s via these kinds of contracts. For instance, under "Maintain needs assessment as is" the conclusion is (incorrectly) "Conservation: ... This keeps addresses available for others. Wealth alone is not sufficient to claim addresses."

You omitted the paragraph which follows - 

".. As in all approaches evaluated in this document, speculators can enter into forward contracts in order to capture the economic substance of a transaction without formal recognition by ARIN."

i.e. the conclusion is accurate but the result (as acknowledged 
in the paper) limited to the extent that ARIN policy is followed.
