You are of course right; I forgot about the poles.  :)  But my point was
not that centrifugal force is in some way dependent on gravity; I was
explaining that centrifugal force is not actually a force, but simply a
manifestation of inertia.

In fact, we are still subject to the exact same gravity whether we are
at the poles or the equator.  There is a slight gradient in
gravitational force depending on your altitude, but this is so small as
to be insignificant.
