Sorry, this discussion is getting somewhat silly or even insane...

There is not a single routing protocol in the world that can deal with
billions of nodes or prefixes...
There is not a single adhoc routing protocol that can deal with
hundreds of thousands or nodes in a dynamic environment, even ten
thousands is beyond challenging.

(lets ignore the fact that most adhoc capable radio technologies
provide a serious restriction on the number of devices within a
collision domain for now)

Saying you want a prefix for a flat adhoc routing domain with 10^10
routing entries is ridiculous.

And you have yet to answer what is wrong about just selecting your /64
part based on the MAC or EUI-64 part of your radio... no collision and
more address space than we will EVER need on Earth.

I think you don't comprehend the scales you are talking about...
especially the technical issues.
