So, you have a unique ability to teach very complex principles outside of the supporting mathematics. Based on your assertions, would it not be possible for others (particularly homeschooling parents) to have a similar ability? For instance, during my freshman year in college, I tutored 5 students in a calculus course without ever having taken the course itself. Simply put, I explained the theoretical concepts in everyday situations. I do the same thing in both the high school economics/business/finance courses that I teach, as well as the college-level programming and networking courses. I would not be so quick to accept the ability to make complex principles understandable as being "unique".
