Totally agreed. If you are only depressing the gas pedal enough to "just get moving" (as in when you take off from a stop) then you obviously aren't bogging the engine by being below the powerband.
Its as you stated, when you try to press the gas pedal too far and you are too low in the rev-band to accelerate at the pace which your gas pedal is dictating. THAT is bad on the drivetrain.
