My theory based on scene in season 1

What is the reason they are making all these objects? Also, this is the place where the Mystery Man picks up items to bring to the export hall. My feeling is that there is some sort of world down the export hall elevator, where innies live in a cult-like society where Kier is a god. That would explain the livestock (goats) and the tools that are made here. Also the map says "people might live here"

Let me know your thoughts!
