It makes sense to me that they'd have to have that kind of aetherial element nearby to be able to use it, since they don't actually use their own aether--they use the aether from the world around them.Kell's roguish charms are only level 15 so I wouldn't know (and canonically it is the least likely class he'd grind) but I'm mostly using other media interpretations of ninjutsu/mudras so I'm not too aware of how FFXIV mentions it.
But due to how the elements work in FFXIV it'd be hard to find a spot that has absolutely no trace of an element. I know the Ehcatl quest that requires you to mine pure water shards/clusters, IIRC, has the item description for these key items mention that they're quite rare.
