Yes of course.  Let's make the assumption that these people are happily 
v6 enabled but need to support v4 for the foreseeable future.

Take, for example, large hosting environments.  NAT isn't an option, nor 
is v6 only at this point.  For them, the only option to provide unique 
v4 addresses for customers is to purchase it.

We may be in luck, and the v6 tipping point happens before the transfer 
market runs out of reasonably-priced supply, and our hypothetical 
example above can default to v6 only.  If that happens, fantastic - but 
I'm not sure I'd bet on it, even given the improved v6 takeup in the 
past year or two.
