That we have time to calculate how everything works. We don’t.
The system doing the calculations is affected by doing the calculations. This creates infinite recursion, which by definition means we can’t actually compute everything
If our universe exists within another universe, the outer universe could calculate and predict everything in our universe, but we cannot do it from within the confines of our own universe.
Having this problem can also be managed by going through the loop. If you original goal was "calculate stuff to prevent bad things", and you can't do it because you're choosing too much accuracy, you can experiment with the accuracy until you find a good middle ground.
We can use super detailed FEM, CFD what not sophisticated science, but sometimes the stuff from the 1800s is just fine.
The loop would need a step that involves recalculating the goal, in that case, not merely actions
