To expand, it makes sense in situations where the "expert" is unable to scale up any farther (lack of capital or labor come to mind) or cannot expand farther without assuming an uncomfortable amount of risk. The second possibility should set off alarm bells for small investors. (Case in point: many McDonald's franchisees struggle to break even while the McDonald's corporation rakes in a steady income.)

If someone really is "retired but wants to help people", I would expect to see the core educational content available for free (or near distribution cost) with the option to pay for one-on-one coaching/consulting services.
