Sure, if we can reassign all IPv4 addresses from scratch, for every network
in the entire world. Lots of luck getting everyone to agree to do that.

And then, of course, you have to keep them perfectly assigned with the
connection topology - i.e. almost no PI addresses at all, for anything
smaller than, say one of the 500 largest organizations in the world. So we're
talking maybe the US gets 100 PI addresses, Europe as a whole 150, Japan 75,
the entire rest of the world gets 75, and that leaves us 50 spare.

Note that means all mid-level ISP's don't get their own address space, they
have to get it from one of their upstream ISP's - and if they change
upstreams, all their customers have to change their addresses.

I don't think so.
