I think the point is that large scale organizations have a certain amount of incompetence within them. Real conspiracies are made to work around that incompetence, either by compartmentalizing and limiting the internal flow of information (intelligence agencies), by being decentralized and resilient to people messing up (eg class warfare still happens even if upper-class people don't all work to further the interests of the upper class), or by not being a conspiracy in the first place (eg if two rich people meet to discuss mutually-beneficial business deals, it doesn't have to be a conspiracy). Imaginary conspiracies just magically work perfectly, with no whistleblowers, no accidental leaks, with thousands of agents invisibly affecting every facet of life to cover up what really happened during 9/11 or whatever.
