You are the one that said the plane would be stationary.
The more speed the plane has, the greater the volume of air that flows around it over the course of time, say
per minute or a second. If the plane is sitting still there is no air flowing. As the plane turns on it's motors, it sucks air (mass) and pushes it behind to inturn push the plane forward. As the plane moves forward, different air will not only go through its motors to thrust it forward, but around it's wings as well creating lift. The faster the plane goes by pushing mass behind it, more and more lift it will achieve.
Put a bottle rocket on a long sheet of paper. Light the bottle rocket. When the bottle rocket starts to advance, rip the paper backwards to keep the bottle rocket still. The bottle rocket doesn't even get the benifit of low friction wheel bearings! The way you are arguing, makes it sound like you could keep it still with no problem.
