The 'Chinese' Theory: For and Against

[ololololo]

Would it really be quicker to design an entirely new writing system instead of simply using latin letters? Is writing daiin really quicker than zhǔ, djoo, ju, or something else?

I asked the same question, but for some reason I didn't get an answer.
If the author came from Europe and understood the Latin alphabet, it would have been unnecessary for him to create a separate, complex phonetic alphabet for the equally complex Chinese. Indeed, it is easier to write characters as ju, zi, guo, etc., because its 1). shortly 2). more understandable to the reader.
Again, let's recall the Codex Cumanicus - the missionaries were more cunning and decided to write the Polovtsian language in Latin.
