IMO the two main points of Kanban (and Agile in general) is limit the size of activities and make the backlog visible. The goal is to empower the team to quickly change priorities. Of course, It's possible to do that without Kanban, but it requires a lot of management skill, and workers hate changing priorities mid-work. And Kanban/Agile also doesn't assure that it will happen.
