Having partitioned transit-free networks is going to continue to be the
exception and not the rule, or at least I hope so...

It does happen. I've experienced it myself.

But I never said that this could never be the case either, in fact I
think you're right; it is indeed entirely possible that this in many
cases is the reason for one network to turn down the other's peering
request. If only one of the networks is geographically large or the
proposed peering agreement does not have provisions about multiple
peering locations (and respecting MED), it's probably even more likely
to be the case.
However, it is also entirely possible that the networks simply are too
stubborn to either accept paid peering, to loosen up on any requirements
of balanced ingress/egress ratio, or to commit to cold potato routing,
or whatever. I suspect that the likelyhood of this beeing the case is
dependant on the size of the networks involved, though.
