Which is better than an access list since, now we are forwarding packets
instead of sending them to a CPU to increase router load.

I don't think ARIN can help the situation. ISPs just need to remove the
access lists from each router in the network and centralize them.
I totally agree with you. However, as always, centralized systems, while
ease management and scalability, everything becomes a trust issue and a
single point of failure or source of problems...
I can think of two organisations which could probably take care of a good chunk of the problem, if people were prepared to leave it up to them. The routing system is already largely dependent on the interoperability of bugs produced by these people, and so arguably no additional trust would be required.

One organisation has a name starting with "j", and the other starts with "c".
