> The red flag for anyone who has studied anything related to electromagnetism is the way it's described as a wall, not a force that gradually grows stronger as you get closer. Forces don't work at distance like that.
You might be taking “wall” too literally. I have no trouble believing that someone would call it a wall even if the force did gradually grow stronger over a significant distance.
