This question is something that we simply cannot answer - and even if
we could, it doesn't matter.

Some people do deploy IPv6 today (whether or not they "really" deploy IPv6
does not matter at all, as long as they need addresses for whatever they
do), so we need IPv6 address policies to enable those to do so.

Other people deploy IPv4 today, and will continue to do so, for a time
frame unknown to me.  So we also need IPv4 address policies.

If the IPv4 pool runs out, we need to handle this, policy-wise.  If it
doesn't, because the Internet stops growing, everybody does NAT, or 
everybody migrats to IPv6, we don't - but we won't know in advance, so 
it is useful to have a plan for the case that it does run out.


So - while the answer of your question might matter a lot to the well-being
of the Internet at large, it has hardly any relevance on the policy work
we do: "distribute numbers to those people that need numbers for their
work, in an open, fair, and transparent way".

(Note everybody agrees whether we do an optimum job here, and much of
what we do turns out years later to be a "good" or "bad" decision, but
that's the problem with todays crystal balls)
