For any kind of literacy, there's going to be a chicken and egg problem. If you suggested to an ancient mediterranean scribe that everyone should learn reading and writing, they'd probably say, "Pah, it would be a huge waste of time for most of them. Very little practical use. They get by with memorization anyway." And they'd be right, in a sense! We don't know beforehand what the fruit of universal literacy will be.
