You could argue all calculus teachers teach the same subject, but all do so with a different point of view, set of experiences, and ability to convey the material.
To further the analogy, a senior/skilled student might have time to donate for mentoring and tutoring, but they're not necessarily of the skill level or ability to create a whole curriculum.
There are some nice guides out there that teach you specific stuff, but it seems short sighted to discount a holistic approach to learning that requires dedicated staff, structure, strategy, and ultimately, a revenue model. There's also plenty of room in the market for different ways of doing this, as different teachers, models, and strategies will appeal to different mindsets.
