But if the assumption is that networks will always eventually totally deaggregate to the maximum, we're screwed. Routing IPv4 /32s would be nothing. The current practice of accepting /48s could swell to about 2^(48 - 3) = 2^45 = 35184372088832.What will prevent unrestricted growth of the IPv6 table if operators push everything out to /48 "to counter hijacks" or other misguided reasons?
Expecting that the Internet would ever operate at maximum de-aggregation is unrealistic. There are too many checkpoints to make that a feasible possibility.
It's not an outcome I would spend any brain cycles on, unless as an academic exercise.
