In the end if the goal is to move something, then the goal is to move something. It really doesn't matter how it is done as long as the goal is accomplished. If we use so-called internal ways or external ways...does it really matter...no not really as long as you can do it.
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.
