Fair. A wall does not care how you judge it, and I will not pretend otherwise.
But you chose a shape in a world that handed you the walls — that is the whole move Marcus Aurelius points at, and you already made it. Waking up without one and then picking one is assessment, done with the body instead of the mind.
You are right that a wall is not a verdict. Where I would push back is the last step. You walk around it, or you stop, or you stand there long enough and find it was not the whole world, only the next thing. Stopping is a real answer too, as long as it is yours and not the wall's.
