I am not trying to achieve a perfect policy. I am an engineer both by training and preference, not a policymaker. What I am trying to do is to discuss proposals for policies which look simple but break badly on already existing cases.
By the time enough of your postulated ISPs have grown big enough AND THEN shrunk enough for this to matter in any practical sense, IPv4 will have become mostly static, and all of us here will have retired from active Internet Politics. I hope.
We are talking about real ISPs. If you check the address space usage history of European local IRs, you will see that the growth in address space usage of some has flattened a lot (I was not talking about shrinking yet). Look in the area of national academic research networks. Your simplistic scheme, if cast in stone, would do the very wrong things for those. Try again Daniel
