Because the point is that the conveyor will match the speed of the plane in order to keep it stationary at any speed it may reach.
If this is the case then the plane will not lift off because it has no air speed causing lift on the wings.
If this doesn't happen then yes the plane will overtake the conveyor and have lift to take off with.
I think the whole argument hinges on the wording of the original question and not with any real possible physics.

in the original statement of the question does it say that the conveyer matches the airspeed of the plane or the wheelspeed of the plane?
airspeed and groundspeed off of the conveyer would work just fine
but matching the wheelspeed of the plane would cause a loop that is just plain impossible

where i think the no-take-off people get hung up is that they think the plane body itself isn't going to move because of the conveyor belt. the plane body will move because the engines will push the air behind it, causing the plane body to move. the conveyor belt moving at the same speed as the plane doesn't mean anything to the plane body, just to the wheels. all it means is that the wheels will have to spin twice as fast as the speed of the plane. but they wont stop the plane from actually moving.
try thinking of it like this...say you have a hot wheels car, and you put it on a treadmill. if you hold the car, the body doesn't move, but the wheels do. if you push on the car body, you can make it go faster than the treadmill. even if the treadmill is on full speed and going 100mph, you would still be able to make the car go faster than it. it doesn't mean the car would be going 100mph, just the wheels.

A treadmill might be able to match the speed...dunno about a threadmill.

It can match the forward speed. But it won't keep it stationary.....
