I just don't understand your beef with the term 'net force'. net and gross may not have been introduced by Newton, but that makes them no less valid. whenever you add up all the forces on an object you come up with the net force, which can be zero or non-zero, regardless of what forces you consider being 'real'. I (as well as several others) sited you as being wrong above because you said that the forces on a single object always add up to be zero, and claimed the Third law of motion as your source. well the third law of motion talks about the net force between two seperate objects. when object 1 pushes on object 2, object 2 pushes on object 1 an equal amount. the net forces between the two objects do add up to zero, but the net force on only one of those objects is non-zero.

But i do agree with you on the point that inertial force is a method of energy transfer. That energy is called momentum, and thats the energy that keeps moons and planets in orbit, and is very important in the game of billiards.
