Also, it bears repeating that you have no obligation as an arcanist to work as a customs official or cargo inspector. It is one thing that the Guild does, but hardly means that every member of the guild does it. In fact, in the class and main storyline it never comes up once. Now, people can certainly rp their characters as Limsa's version of the TSA, but nobody will call you on not doing the same because the game's lore never implies that you have to. Arcanists work as cargo inspectors, but not all arcanists are cargo inspectors. Any implication to the contrary is a false tautology.
If you're character doesn't care for Limsa, have her go through the Guild to learn the basics and then bolt. The SMN job comes out of the ACN, sure, but the SMN trainer isn't even in Limsa, but rather in Gridania. The Arcanists' Guild doesn't teach the sort of summoning that the SMN does; that's recovered ancient Allagan knowledge, if I remember correctly. The Sons of Saint Coinach are more heavily involved in summoner business than any of the guilds or city-states (excluding Sharlayan, the Sons themselves being Sharlayan).
