Either your proposal makes a difference here, or, your above statement isn't relevant to the discussion. If your
proposal makes a difference in this regard (encouraging LSN), that is a negative IMHO.

I actually don't assume that at all, but, that's OK. There may be other assumptions built in. I would argue that increasing
NAT does not increase the efficiency of address utilization, but, merely increases the number of users on a single
address while decreasing the utility of those addresses. The net efficiency remains roughly the same if one considers
the utility factor as part of the efficiency equation.
So, again, either your proposal will make a difference here (encouraging NAT) or it won't. If it doesn't, there's
not a lot of relevance to your statement.

> Owen, any single entity is limited to a /12. I trust the ARIN staff to be able to determine whether the entity is a sham company, and even by the size of your limited pool, a /12 can't corner the market. So maybe we can at least temper the fear that a speculator would enter into a 4 minute market.
It doesn't have to be a sham company, it can simply be a subsidiary. For example, last year, a certain
cable provider got a /9. They would have no problem whatsoever creating 8 regional operating
companies each of whom needed a /12 in my estimation.
The /12 limit is both absurd and utterly useless in having the effect you claim. All it would really
do is penalize large providers (note, I'm seeking fairness, not penalties for either side) and
