If country X were taken out of the root, it would take coordinated and concerted action by a large number of people around the world to restore service to that TLD's domains.  That sort of effort would come into existence only if there were widespread outrage.  It's not something that is easily done nor easily tested in isolation.

Put a another way, the impact would be about 2% per hour." This means that a daily run of the projected EZOP application is enough to keep an HomeRoot in tune with the top zone reality?

Perhaps I haven't been following closely enough.  What's "EZOP"?  What do you mean by "name servers declared via the TLD zone files which are not listed in the root file"?
