What does component deactivation do?

I have been trying to have events in an actor component not trigger and thought that deactivating the component would do the trick. But events still do tick. At least those that I bind to in the BeginPlay of the component.

That makes me ask what even is the purpose of deactivating a component in the first place. What benefit does it give us apart from some nebulous performance benefits?
