think about this...

It is so obvious it is complicated, if that makes sense.

I suck at life.

Of course the plane has to be moving relative to the air around it (or the ground if that makes it easier).

this is it, you need wind over the wings for lift!! a plane cannot get in the air without lift! wtf, i can't believe noone gets this

Please let me know what company you end up working for so that I can stay off their planes.

It's very much like a float plane taking off from the water (where there's also negligible friction).

No it is not. It would be like a float plane taking off from a river that is moving at an opposite speed of the floats. WOULD NOT TAKE OFF

To simplify:

1. Plane on a runway. Takes off
2. Plane with locked wheels on ice. Takes off.
3. Plane with locked wheels on runway. Doesn't take off.

Note that #3 is the same problem that OP phrased.

Please explain specifically what FORCE is stopping the plane from moving forward (relative to the atmosphere, NOT the conveyor belt).

#3 is nothing like what OP phrased. Explain how the wheels will move at the same speed as the plane in this example.

isn't the whole premise of this post is that the plane isn't moving?
