On the one hand you are correct, on the other hand I am, on the gripping 
hand we both are.  If you are a company that can (and will) use a 
significant portion of the /64 address space you are assigned, then 
there is a huge benefit and the company will use "one" address in the 
remaining 64 bit address space instead of the thousands assigned out of 
the 32 bit address space of IPv4.  (Infamous last words here) This 
should be plenty for the near future.
