The fact that you do not like needs-basis does not mean that it is obsolete thinking.

Quite recently, we have seen repeated demonstrations of strong support for needs basis from the community.
As such, I think it is inappropriate to characterize it as "obsolete thinking".

Yes, but policy must balance those concepts where they conflict in order to be effective. This statement may not be the best possible way to express that, but it is a valid expression of that concept.

> The idea of authorizing intrusive "accounting of resources" is precisely the opposite of the way we need to be going, both in IPv4 and IPv6. We should let the market allocate transfers of the fully-allocated IPv4 numbers, and current policies, which give organizations blocks based on the number of networks they claim and some fill ratio, for IPv6. There should  be flexibility in the methods of conservation used. There is no need to specify concrete methods and practices in a principles document. That is just a mistake. 

Nothing in the NRPM is inherently permanent, so this argument is questionable at best.

Needs basis and documented justified need have been required since the days when Jon Postel tracked IP address assignments in a notebook, so I am not sure how you can claim that this concept was developed in the final death throes of IPv4.

I'm well aware of your desire to move to a world where IP number resources management is as dysfunctional as radio spectrum management is today. (One need look no further than the history of the 220Mhz band for an example of this dysfunction).

The IPv6 portion of your argument is in favor of policies which require documented justified need, so you appear to be arguing against yourself here.

>> 0.2. Hierarchical aggregation (Routability)
> I agree with the comments Bill Herrin made about this earlier. " Policies for managing Internet number resources must facilitate scalable routing." Scalability is what we care about, not necessarily hierarchical aggregation or anything more specific. Remember, these are supposed to be long-lasting principles, not a codification of what we are doing now, and not a specific set of policies. Let the community set the specific policies flexibly going forward.

Since this is a document being developed by the community and which will require the consensus of the community to be enacted, I'm not sure how you can claim that it is not being left to the community itself.
