Barit,
Yes the fuselage will provide some lift, but as it is (hopefully) symmetrical, it will provide as much of an upforce as a downforce. This is why you require a positive AoA to gain that small amount of lift. The fuselage is a source of lift in all scenarios, but is so small that it isnt talked about, except apparently here.
The lift coefficient alone wont be enough to allow most planes to fly straight and level at knife-edge, so certaintly cant be used as a standard example of flight. It requires additional thrust at a positive AoA to overcome the weight as illustrated by a harrier, rocket, helicopter.
Anyway, this thread is about how the force of lift is generated, and the fuselage in your example creates lift the same way that a wing creates lift normally, but due to the extreme AR of (most) a fuselage, lift generated will be insufficient for flight, requiring vectored diversion of thrust upwards to help overcome the weight.
That's all im trying to say
