Seems to me that if the inertial force is equal and opposite to the motive force, the body ain't going anywhere. Therefore, it would be "restrained from movement." For a body to go somewhere, the motive force has to be greater than the inertial force.

and thats the exact point that Richard danced around. there may be an equal but opposite force, but it is never on the same object. If it were on the same object then the forces would cancel each other out and, by Newton's second law, there would be no acceleration.
