Every company needs smart people enough that master the business and skilled enough to sense what are the business needs at all times. They are usually called "Business Leaders". Holacracy is just a tool that don't remove such org. needs. It allows those people - once they get how to use the tool - to serve even in a more efficient way the purpose of the circle/org. by processing all the tensions they are able to sense (the "business needs"). Again Holacracy does not get rid of such skilled people, it don't remove the necessity to have into the company such people; in fact it's just the opposite & it allows also everyone to process any business need they may sense for better expressing the purpose of the Org.
