Failure of routers to handle the number of identifiers being handed out.

ARIN's current fee for folks who have only direct assignments (of whatever 
protocol(s) or size) is $100/yr.

Your "given" is currently false.  ARIN policies are influenced by those that 
live in the DFZ (i.e. big ISPs), and since those folks are scared of routing 
growth, ARIN's policies are crafted such that only those folks who "deserve" 
a routing slot get one.  AFAICT, that is not going to change until we get 
the ID/LOC split everyone keeps talking about -- then DFZ players should 
only care about LOC growth, not ID growth.

The current consensus criteria for "deserving" a routing slot can be found 
in the NRPM.

ISPs need /32s so they can assign /48s or /56s to folks who don't "deserve" 
a routing slot of their own, which current accounts for the vast majority of 
users/orgs on the Internet.

Please note that I'm not necessarily defending the above thinking, just 
explaining it.
