I've actually used this very question in Levinth's character. He's a tradesman, and seeks to expand his trade empire across the lands of the three city-states in order to ensure Ishgard has a steady supply of goods. Being the heir of a noble family, and a 'born and raised' ishgardian, he sees the task of helping to sustain his home city as something that is simply expected of him. I wouldn't be surprised if other 'stranded' ishgardians were also doing something to help their mother nation, despite being stuck in other lands.
