Well yes it does require some dedicated PMs, owners and leads. If you are a smaller operation that does not have this, sprints might not be as beneficial. But if you are working for anything at scale as a developer, sprints aren't necessarily to track every hour of your day, it is to give you a structured path of things to do without having to know every detail about the bigger picture/compromises with product/prioritization. Also as a developer it gives you leverage because you were given certain tasks for the week so when someone comes along and tries to inject "high" priority item X, something else has to give.

I found before I was on the planning/lead side, it was hard when you did not have this structure. People would still shove in "small" tasks without a sprint structure and then months later it is hard to explain why a big project did not ship on time. So if done right and not abusively by oversubscribing devs, it is a great too for both sides.
