We need someone at the top with the big picture view to direct resources.
Thanks for the insight, comrade. That has never worked well.
Someone at the top running the day-to-day of an entire economy? I agree, that never ends well.
Someone managing a disaster or emergency? Absolutely necessary. When I was on a fire crew, the Incident Commander had all the info, and told us where to go. We had leeway to do what we had to when we got there, but we didn't decide where to go.
If you ever find yourself in a fair fight, your tactics suck.
