Mechanical movement does not preclude other types of forces. E.g., one can use electrostatics (say, the repulsion of electrons) to cause movement of masses.

Yes — but what I was trying to say was that mechanical movement is necessarily always electrostatics. ( And thanks for that word.) Under normal circumstances, nothing ever really “touches” anything else. So what appears to us to be purely mechanical is actually electrostatics visible on a macro scale. Since what is actually causing the motion is the electrons on the bodies’ surfaces repelling each other.
