This is another case of trying to have our cake and eat it too.

ARIN doesn't control or have anything to do with routability or global
routability of prefixes.

ARIN only provides uniqueness and registration.

So, giving someone a globally unique prefix does not necessarily mean
the same thing as a globally routable prefix.  Routability is  
determined on
a case-by-case basis by each AS to which the prefix is advertised or
attempted to be advertised.  It's not ARIN's business or responsibility
to get involved in routing decisions, and, the more these types of
discussions continue, the more I become convinced that we really need
to stop tying address policy decisions to the current set of routing

Jordi pointed out a number of scenarios in which globally unique  
are very desirable, yet, will not be globally routed.  There's no  
reason we should
avoid doing this in IPv6 where numbers are not scarce.  In IPv4, we  
had a
situation where there simplly weren't enough numbers to address the
publicly connected needs of the internet in the long run, so, there had
to be a priority give to making those unique.  As near as I can tell,  
the ONLY
problem IPv6 still solves out of the entire list of problems it was  
intended to solve IS the not enough numbers problem.  As such, it does
not make sense to me to act as if that problem is not solved in IPv6.

Again, I don't see how that is relevant to ARIN policy.  If the ISP  
is not commercially
viable, then, they will stop renewing their ARIN resources and the  
can be reclaimed (or, they will be absorbed by the acquiring  
entity).  Either
way, I don't see how ARIN should be passing judgment on peoples business
