You very clearly wrote that Chinese would become an incomprehensible mess if written in Pinyin.
You first stated that there would be a severe loss in fidelity in switching to Pinyin. Then you gave an analogy showing how removing various non-phonetic elements of written English would make it an incomprehensible mess. Immediately after that, you said that the same applies for Chinese.
I'm objecting to your argument that Chinese would be an incomprehensible mess if written alphabetically.
