Indeed.  Right now, the cost of inefficiency is zero and the benefit to 
fixing it is zero, while the cost of fixing it is usually nonzero.  It's 
not surprising that we've seen the results we have.  Attach a monetary 
value to the resource, though, and the entire picture changes.

Much of the blame for underutilization and "waste" is placed on end-user 
orgs with legacy space, and for them I'll add another category:

* Excess space that was justified at the time issued but would not be 
today, due to policy changes

That is a _huge_ consumer of space -- several /8s and thousands of /16s.
