Dear Masataka,
Would you please enlighten us by sharing how this scheme would work – I’m intrigued. Given the current rate of consumption I don’t see how we could possibly not hit the last /8. If you think the single act of mandating NAT will make the rate of IPv4 consumption stop on a dime it would have happened long ago and at the same time would not change the non-technical aspects of the problem at all. Regardless of how exactly you do it, adding NAT (or any other form of complexity) inevitably adds cost. LIRs on the whole are strongly cost-driven, especially in the current financial climate; investing in more kit than strictly required is a no-sell business case.
Just using up more IPv4 is cheaper in the short run than any other alternative, so it will be the preferred way for a lot of people.
Can we please have the discussion about what to do with the last /8 at the risk of not ever needing the bit of policy that comes out of it? The least thing it does is showing the outside world that we, as a community, care.
Best,
Remco

Why?
Assuming reduction of address space consumption by mandating NAT,
I can't understand how the last /8 could be reached before IPv4
will be replaced by something not likely to be IPv6.
Could you elaborate?

I don't think it off topic to discuss whether there will be the
last /8 or not.
It is a fair counter argument against a policy proposal on the
last /8 to say there won't be the last /8.
