You are pitting a pair of choices against each other as if they are
the only two options, when the reality is there will be a continium
of solutions in the middle.
ISP's will come back for more IPv4 space and get told no. I would
hope a savvy ISP could set aside a /28 of their previous allocation
to use for transition technologies at that point. I pick on that
size only because it's a popular suggestion of how much space we
should give the ISP from the /10. The more we can encourage folks
to make these sorts of wise decisions, the longer the /10 will prove
Even if the situation you describe comes to be, where folks are
monumentally stupid and give out every last IP of their allocations
keeping nothing to run a transition box your dire consequences still
come true. Giving a provider who receives a /28 or two from the
last /10 will not change their competitiveness against another
provider who still has half a /8 available.

I agree with your statement, but I also believe there's enough
information to get everyone on the same page. When we have only a
/10 left, everyone is screwed. There is no using that /10 to make
even 1/1000th of the people happy. We're out, done, and if your
business depends on it you might as well go ahead and turn out the
lights. I've not seen a single person suggest how the last /10
could save businesses that have failed to plan.
The last /10 isn't about making a business with no IPv4 able to
compete against someone who still has half a /8 left. That is
frankly, laughable. What it can be about though is help for those
who planned well and ran into unexpected consequences. The guy who
deployed transition boxes across his entire footprint and then
purchased a smaller ISP that did not plan so well, but also expanded
his footprint. He's up and working, but latency to those transition
boxes is bad for his new customers. He planned well, so maybe we
can give him one more /28 for a pop in the network he purchased.
We need to get out of the mindset that if someone has totally ignored
IPv6 transition we have something good waiting for them in the wings.
