The value of many industrial vessels such as the Andrenidae would not yet come into play unless the expeditionary fleet reached the Red Ocean.
Right now, the Larkinson Clan did not have to worry about being deprived of many essential resources. Even out here in the galactic rim, humanity had already been rooted here for several centuries. The local economy and infrastructure was well-developed and the Larkinsons could buy any readily available goods at any major port system.
In fact, the efficiency of many large scale mining, resource processing and production companies was so high that the Larkinsons would actually waste a lot more time and money trying to mine and process resources themselves!
Unless the markets became inaccessible for some reason, there was no reason for the Larkinson Clan to make immediate use of the Andrenidae.
