Can you think of a very simple story? A story that you know that it is done with just one simple acceptance criterion and…

Yes, that is a good story… a small story. The narrative/intent is simple, one can get the gist of it in an instant. No ‘spinning of wheels’ trying to understand it; it gets done in least reasonable time.
With that kind of a small story, can you imagine how fast you can churn out stories after stories?
You got it… a good story is small because of three things it brings: reduced complexity, increased throughput, and faster user feedback.
