I don't think absence of evidence is evidence of absence, ESPECIALLY when our viewpoint character for whom all quests in the game are written has a special talent that allows them to speak and understand any language in the multiverse, including Dragonspeak and Ascian.
I agree that "Eorzean" (Hyuran Common) seems to be very widely spoken, but I strongly disagree that means that all the other languages in the world are dead or dying and that nobody's player-character would speak them. English becoming ubiquitous in the real world hasn't killed off Spanish or Mandarin or German. I admit I'm no linguist, but as far as I'm aware, the introduction of English overseas has created MORE languages, in the form of pidgin dialects. Not less.
People are treating it like "Eorzean is the only spoken language anywhere" is the only logical conclusion from the lore we're given, and that's just not true. It's one possibility, but it's not canon, and it's not a foregone conclusion from the evidence we have.
