How about the machine population? How about self-replicating systems?

I think considering the size of such systems as a function of
the size of the human population is quite reasonable, in terms
of thinking about natural and economic limits to growth.

How about geography-based address allocation, to go away with global routing

That is a whole discussion in itself, but in any case it surely
won't be part of 2000::/3. Additionally, the number of prefixes
needed for any reasonable geographic scheme is quite trivial
compared to the trillions available.

How about InterPlaNet, such as LEO routers, solar power
satellites, controlling industrial production on the Moon and elsewhere?

Probably also trivial numbers compared to 15 trillion /48s,
but if not, again, we are not limited to 2000::/3 for ever.

EOF for me on this sub-topic.
