I think it's safe to say that "to learn it to a certain degree" is exactly what people want out of books like this. And "to learn it to a certain degree" is fundamentally different from "cannot be learned". Nobody expects to become a world famous typographist by simply following a tutorial. What they can do, is acquiring an applicable skill for their occupation. And of course violin can be learned to a enjoyable degree by most people if they wish to do so. You'd need fair bit of talent to make a career in the classical world, sure. But to play it enjoyably is something an amateur can certainly achieve. (Speaking as a talentless amateur violinist)
