Title: Playing gravity and inertia...

     In my opinion , we can combine in some way the gravitational fall  and the rotational inertia effects ( centrifugal " fall "...) , so to imagine  a continuous "self" unbalance ( "free" motion...) !

Average potential energy of mass does not change in a closed loop. Several such systems combined does not change that fact.

"we still don't know how a gyroscope stays pointed in a fixed direction" - Yes, we do
 ;)
The spinning mass of a gyroscope is forced to follow the spinning solid mass. That's one.
This spinning mass do not want to change direction angular to this motion, just like any other object that flies through the air. It does not suddenly change direction unless a force is doing so.
Therefor the gyroscope stays fixed.
However, there is something called precesseion, when the spinning gyroscope starts to wobble, but this happens only if the gyroscope rests on a pin towards the ground or a table. It becones unstable due to the force of gravity.
