Class changing, are we unique?

As for Soul Crystals, implicitly anyone who is capable of resonating with a given Crystal can learn the skills within it. NINs pass soul crystals down in their hidden village for this express purpose. What makes us special is that, implicitly, the Echo and/or Blessing of Light lets us resonate with any and all Soul Crystals. So while others have to train for a lifetime to develop their skills, we just hack into Soul Crystals to become proficient in the arts we can go on a deicide binge in an afternoon.

Continuing with Astrologian, Leveva's grandfather sees his crystal glimmer in your presence, immediately tosses it to you, and nerfs himself of all his job skills in the exact same way we do when we unequip soul crystals.

It makes me wonder the mentality behind job crystal resonation. Is it an honor to pass it on? How many people have them?

...and nerfs himself of all his job skills in the exact same way we do when we unequip soul crystals.

That's an interesting question though, since AST is a pure job with no class attached, and all it's skills are jobskills. So what did he actually become by unequipping the soul crystal?
