What you are saying does not disagree with my point.  I am not talking
about ARIN's responsibilities.  I am talking about what, if any, rights
are conveyed with an IP address assignment from ARIN.  ARIN doesn't
have any rights to control people who run routers, and, IP addresses
delegated by ARIN don't  come with any such rights, either.

I'm not saying ARIN isn't responsible for making sure that what they
issue is proper.  I'm saying ARIN has no ability to enforce what
some other ISP does with the data.  ARIN can't control if Verizon
chooses to route some random address to one of their customers
instead of to the organization that ARIN issued the addresses to.
There's simply no way ARIN can do anything about this.

No... What I'm talking about would be more like saying that a credit-
reporting agency isn't responsible if MC issues a card number
to someone and VISA issues the same card number to someone

(Yes, I know that V starts with 4 and MC starts with 5 exactly
to avoid this, but, it's the closest I could come using the
analogy presented.)

The reality is that if VISA and MC do create such a numbering
conflict, the credit reporting agency really can't do much about
it.  I don't know what level of authority is granted to the numbering
authority for PCI stuff, so, let's just accept that the analogy doesn't
fit if you over-analyze it and move on.
