The assumption that the goal is (only) to move something is incorrect. In many cases, the "how" is just as important of a goal as the "what" (in some cases, the "how" is all that actually matters).
To use an extreme example: I could end hunger and overpopulation by killing off 90% of the world's people.
To use a better example: I could move a 200lb person by going to the gym every day and building muscle until I can lift a 200lb person.
Or you could train "IP/IT/IS" everyday, building "mental constructs"? until you can move a 200lb person.
Kevin has brought up many good points.
Please explain, exactly why is the how of "IP/IT/IS" all that actually matters within our context? What distinctions are you making?
