What mechanism does this theory use to overcome the effect of 9.8m/s/s downward acceleration (ie, gravity)?
Well clearly in real life, for a given aircraft mass and force of gravity, you have to produce lift to counter that gravity, and lift production will require thrust and therefore power to overcome induced drag (at the very least). So this was just a theoretical point, to clarify that drag cannot be ignored.
On the other hand, minimum cruise power will keep you airborne, and overcome both induced and parasitic drag, as shown for example here.
