The summoning of a faery is more complicated than a simple carbuncle. It involves actual anciant nymian tablet texts and sigils (as seen in the SCH quest), and a deeper understanding of the nymian tactics described inside. That makes faery summoning more of a lost art indeed, knowing that most old nymian scholars used to have faery companions.
BLM would tend to burn themselves to death without their crystal, but WhM can't simply access the magic (Succor/White Magic) as taught by the elementals to the padjals. Wether this was the case or not for anciant Amdapori magic is left to speculation I think. I suspect that old Amdapori White Magic might differ slightly from the one controled and granted by the elementals to the padjals of the Twelveswood.
It is unclear for some jobs if they really need their crystals as a key for their art to work or not. It's definitely the case for BLM and MCH for example, but rather ambiguous for WhM, DRK, and probably not necessary for jobs like Nin, BRD, etc.
In any case, a soul crystal is a repository of skills and memories not that dissimilar to starwars Holocrons, that will only open to the people with the sufficient base knowledge and affinity to the art. Some of them, like BLM, also act as essential keys to the job for it to work properly.
