Some of those stones are also necessary for some jobs to act as catalysts or channeling stones, like for BLM (Gems of Shattoto) or MCH (used in conjonction with the aetherotransformer). I also suspect the WhM soulstone to be necessary to access the modern version of Succor (Elementals credentials of sorts).
Soulstones are of course crafted. Your best source would probably be the Anima series: the Anima is born of various advanced crystal technics able to concentrate enough aether and bind it to a soulstone so that it can eventually form an embryo of personality, evolving eventually to a full fledged conscious being.
Your usual soulstone would probably require a lot less specific and rare materials since you don't ask it to hold the crucible of life itself, though, just a repository of memories and personas.
So yes, since the first users of a soulstone have to actually print their knowledge and persona on it, those soulstones are blank and empty at first. Same for the anima soulstone, that we get to replace a few times when she grows (the last one most notable step being the ilvl260 where you require pneumite for a node to craft it, which shows the amount technology required here).
Also in short, creating soulstones is not something trivial.
