It wasn't idiocy. The Soviet destruction would be on the ground, the Luftwaffe needed to be able to support the ground forces. Heavy bombers are only required when you need to strike long distances or across areas that your ground forces cannot reach.
The Luftwaffe only needed to support the Heeres during Operation Barbarossa. Heavy bombers were not needed against the Soviet Union because the ground forces could have reached the factories and production facilities.
That is to say, if Hitler hadn't messed with the strategic planning.
The only time the Luftwaffe would have needed heavy bombers was against Britain during the Battle of Britain. The only reason the USAAF and RAF had massive amounts of heavy bombers was because we were striking at the enemy while being unable to use our ground forces against them.
