Yes but it can get pretty noisy when a component that is deep down needs access to some information.

Redux decouples component structure from information access.

This is useful when you have some little button for example that should look different depending on whether the user is logged in or not.

Without redux you will burden each and every component in the hierarchy to manage that state up and down.

With redux that button can hook itself into the state and be dropped anywhere without burdening its parents for any state management.
