All I'm saying is, for the time being, catastrophic predictions that we're making the
same mistakes as with IPv4 are a little dramatic and possibly premature. I agree with
you that if every human gets a /32 we won't get very far, but for the moment, we still
theoretically have about 13'000 IP addresses available for each kilogram of matter on
Earth.
Until we create matter out of nothing, I still think we're on the safe side. I don't
doubt you disagree, and I'm ok with it :-)
