> 2. The writing system, which because it's not phonetic requires essentially the same level of effort as learning an entirely new language (beyond spoken Chinese).

This is an interesting observation. Another one that I sometimes mention to my friends who didn't have an occasion to learn Chinese before is that in this language speaking, reading and writing are actually 3 separate components. You can read characters without knowing how to write them properly or even remembering them entirely. Lots of my Taiwanese acquaintances forget how to write certain characters, because nowadays most of the text they write is in bopomofo on their phones. Bopomofo represents sounds, so basically knowing how an expression sounds and being able to read the character (pick it from a set of given characters for the chosen sound) is enough to "write" it.
