I think you underestimate the tendencies of ISPs all over the world to leak peering routes towards their transit providers.

Contrary to popular belief, leaks through peers in remote regions do not always result in huge AS_PATHs which are never selected by the rest of the network. For example, some of the most remote and poorly- connected ISPs that F is announced to from local nodes are transit customers of international, default-free carriers.
