Nobody can type up a GIF image, or Word document in a Notepad, yet files of both those formats exist. The answer obviously is tooling.
If a format with sane separators was common, so would editors that could edit that format be.

Sure, but that's a hypothetical future editor, not something that currently exists.
Edit to add: I also disagree with "sane" in that context. New separators won't solve anything. You'll always need escaping/encoding/encapsulation; get that right and everything else follows. JSON is comma-separated and does just fine.
