its a tricky scenario, i'm sure it'd be handy with no "chain" of management and approvals smothering your every move, you'd be able to get things done a lot easier.
however, with the freedom comes responsibility and in our arse covering world of business i'm not sure how that works.
managers do serve a purpose, but that purpose is to steer and guide and always keep an eye on the big picture, which is hard to do when your being bogged down in details, a business with no leader should surely have no direction, or be pulling in several directions at once with people implementing contradictory plans.
theres a reason why the vast majority of big organisations have top-down management structures.
