That's not what I said. I did suggest however that to the average hobby Aikido practicioner the superior stability, power generation and stress channeling/absorption one can gain through internal training aren't of that much use. Of much more use is what happens when you can redirect forces with little to no overt movement.
Except you don't get one without the other. At least as I understand it, the stable platform is the literal foundation for everything else that internal training does.
FWIW, I agree with Christopher that most people aren't as stable as they think.
