Of course.  Routing protocols are no more an ARIN issue than addressing
policy is an IETF issue.
What I ask is...is it likely in the next 15 years to have a scalable routing
protocol that makes the issue of PI addressing of end-sites mute?  25 years?

Are there no other compelling reasons to need...desire... PI space?
If it really IS simply renumbering, then
