Crafters have no right to get their own Chocobos

[NoctisUmbra]

Then, why "Final Fantasy" XIV has no basic chocobo that I can have on my own?

I don't work for them. They did say they are looking into chocobo breeding though.

In the end it could simply be that they want personal chocobos to be something only available to players ranking a battle class at least to 25. Behind all the lore that could be a primary reason. It certainly wouldn't be a bad one either.

The more areas of the game you participate in, the more content you gain access to. When it comes to battle classes, the idea may simply just be "all players are expected to rank battle classes." Given that non-battle classes are considered support classes that are secondary to battle classes, it is a valid idea.

SE is not excluding you from their personal GC issue chocobos. You are excluding yourself from them by not ranking up a battle class.
