Partially. Certainly the part about forcing the rollout of IPv6. But the 
rest of it deals with ever increasing utilization requirements and 
higher and higher bars to meet to get allocations. Perhaps separating 
the two would be more fruitful?

"Used" takes on different meanings, depending on who you are. For an 
ISP, I would want them to bundle a /64 (or maybe a /48, open for debate) 
with each IPv4 address given to a downstream customer. For an end user, 
DNS populated with AAAA and A records for hosts located in the netblock. 
I'm sure others can think of better/more things.

The thing of it is. Once some tipping point is reached, I think you'll 
see existing holders of IPv4 space coming to ARIN to get IPv6 space so 
they can roll out IPv6 to existing customers and get them dual-stacked 
as well. Then the ball is rolling... Once enough folks are dual-stacked, 
then v6-only can survive on it's own merits (years away, but we have to 
plan the route).
