I think the author completely misses the point or never worked in a proper agile team.

Imagine running a marathon without mile markers. Sprints are like mile markers they help you know and adjust your velocity and capacity to reach the end goal.

Without these sorts of tools you are just running without any sense of achievement or tuning to your teams performance.
