While I suspect you're not wrong about either inefficiency in large, well-funded media organziations or the efficiency of Rogan's operation, comparing his podcast to anything but a substantially similar TV show is hardly a fair comparison. Even a relatively low-budget scripted TV series is going to require a cast, writers, props, sets, costumes, hair and makeup, lighting, camera work, craft services, transportation, significantly more editing and postproduction, the list goes on, plus directors and producers and administrative personnel to manage all of this.
