Words are easier to read and write even if you do not understand their real life meaning, especially since computers are still made with a primary input device for typing words, and allow for way more distinct and readable variations (26 letters + numbers vs just the few symbols on the keyboard). And while they aren't that helpful when learning as a kid, they can still be very helpful later when you have to tackle way more - remember that the argument was about kids learning.
