If you always keep your right hand on the wall, how exactly would you ever get stuck in a loop? The only case I can think of is if the exit isn't on the outer wall, but through a hole in the middle or something.
Sure you can have bits of wall pieces in the maze, but you'll never get into contact with those, as that would require you to remove your hand from the wall.
> Imagine, for example, deciding to put your right hand on the wall of Taylor Swift’s pupil. You’d literally get lost in her eyes!
You would have to first take your hand off the wall in order to put it on the pupil. The idea is you put your hand on the wall at the entrance and never take it off, not put it on arbitrary walls.
