[WH40K] All opponents of the Imperium are annihilated... what next?

What would happen if one day, the Orks, the Tyranids, Chaos, the Eldar, the Tau, the Necrons, etc all disappeared?  Nothing else has changed, all faster than light technology remains, what's the Imperium of Man to do now?

The Imperium's biggest enemy is the Imperium. The imperium stands not because it is powerful. It stands because it has to be. 
  The innumerable threats legitimatizes the suffering the Imperium does onto its citizens. Crime is allowed because it feeds the space marine chapters. Workers are worked to death because you need to arm the mighty armies of the ' mighty' Imperium.  
   When that need is gone, you cannot step on the citizens anymore. Before they tolerated it for the collective good. But now, it is gone. You cannot push humans anymore. Then, the mighty Imperium of man will crumble.
