Abundance can also lead to expensive and undesirable behavior called
atrocious waste  which eventually leads to scarcity if  appropriate
constraints aren't utilized.

IPv6 is abundant, but it's not abundant enough  that the same scarcity
problem can't accidentally be created as with V4.

It's a  salient and justified fear, given the experience with IPv4.
Consider what happens if the expoential internet rate of growth over
the next 30 years expands in the manner it has in the past 30 years.

It's conceivable there could be a quintillion internet hosts before 2020.

And with V6, many of those would consume an end site.   If 1% of those
quintillion is a logically  end site that gets a /56, that's
13% of the IP space.

Also, a forgeone conclusion is major new uses of IP addresses; it's
the reason end sites get a /56,   so they can have multiple subnets.

It's conceivable V6 users could want more,  some may even be giving
end sites a /48  instead of a /56 or /64.
There must be some specialized app that really burns IPs for this

Well, there aren't enough  IPs  in the IPv6  address space  to assign
1% of those   10000000000000000 end sites  each a  /48,  so you have
exhaustion in that case.
