The thing is it's sorted only after PinYin is invented, sorta proves the point.
You can't easily compile an encoding out of it, but for alphabets it's intuitive to invent an index for each letter into dash-dots as morse code. It's extremely difficult to do so for Chinese.
Back to the topic, OP talks about "Character amnesia", if you think Chinese characters as emoji, yeah you talk about actions represented in emoji, but you forgot how it was drawn exactly. You can't sort emoji, and emojis don't generally have a sound.
