I think conceptually, Arcanists should be thought of as both having and using far less Aether than either Conjurers or Thaumaturges. The precise equations used to manipulate it allow them to create major effects even from the sort of small energy expenditures that the body can safely handle. (This is how they avoid the dangers Sylphie and her mother ran into trying to use Conjury from personal aether alone, since Conjury requires a greater amount of raw power.)

This isn't fully expressed in the amount of MP we have and use, though. Which could either mean I'm wrong in how I'm thinking of it, or could simply be a case where gameplay trumps lore (since ACN having/using far less MP than the other casters would make it difficult to correctly balance cross-class skills). Perhaps we could say that MP is simply measured by a different scale for different classes.

Perhaps they would fill up eventually. We know that Arcanists normally keep replacing their books periodically (as we do ourselves every time we upgrade them). The only question in this regard is about the Miqo'te girl we train with and the book she's so emotionally attached to. We know it's highly irregular for her to keep the same grimoire for so long, but we don't know why she hasn't run out of room in it.
