I still don't see Rowena and Lolorito's actions as being equivalent to Eorzea acting in an imperialistic way. They are individuals who happen to be Eorzean. We have an uneasy relationship with them at the best of time, and their actions don't represent the Alliance - but at the same time, the Alliance isn't going to reach halfway around the world just to stop them from setting up shop in a foreign country. That's the other country's business.

Yes, if a foreign country was doing it to Eorzea, they might rightfully intervene - but then in this case it's Hingashi that is fully entitled to strike at Rowena and EATC's dealings on Val, or claim the island for themselves since it's in their territory. And they have not.
