I'd think they would struggle, while relying on the Zoners heavily a large portion of their supplies must come through Jump Holes and must come from Pirating, so naturally i think it would be fair to assume that they would go through famine, riots and uprising, everything you would expect from a society, or societies under massive economic and agricultural strain.
While they could survive on good will for the time being that wouldn't last, millions would die. And they would likely either find an alternative or find a way to open the holes again. But the results would be dire in my estimations.
