Most leaders in Captain Lochport's position would instantly accept the offer. The support of a noble was priceless, especially in those remote areas of the regulated universe. Nott Station was bound to benefit greatly from it.

Nott Station could have already garnered some relevance and better finances if the Captain had engaged more deeply with the criminal activities in the area. He didn't because it would have given the structure the wrong kind of exposure and fame, ultimately putting it at risk.
