The world was literally ruined into another depth at that point and whoever resisted to that point were 1. Decimated. 2. Lost. If there was a timeout then at a civilization level humanity already collapsed beyond recovery, even if it took what seemed to be a single generation to bounce back into it's current developed state. The game has so far introduced cloning, which is also Administration technology but the genetic diversity of the population would be more limited than it is now. So the only option is to integrate the next world's population with the Six Administration cities, and gain more political power than the natives of the new world.

But developed nations established outside of the Administration already had more than 3 generations worth of heritage even though those cities and societies should have been annihilated due to no dimensional ships and anti CO weapons to reclaim their territory.
A footnote that the Administration was more secretive to what they are now and the existence of Counters was never public after the failure. Those societies and cities outside of the Administration's underground influence had no chance of survival. Most of their military manpower of the Administration were exclusively clones if they weren't counters or researchers but the weapons of the Administration could combat the current average level of corruption.

So whoever still works for the Administration, and were forgotten by them knew what really happened. Otherwise there would never be a Salaryman X story angle if the current Administration didn't process the survivors of the previous world.
