In general, you're right.  But we have ~60 years of experience teaching
us that *every* successful computer architecture runs out of address
space.  I see no reason to think that today's models for home address
space will be the exception (unless, of course, IPv6 is unsuccessful,
but in that case it doesn't matter much what we do for allocation
policy unless our actions are sufficiently stupid to cause the failure).
