In any case the controversy had ramifications that extended into many seemingly mundane aspects of the Cloud Ark program. If Izzy was going to maneuver with Amalthea attached to it, then the structure holding the rock to the space station needed to be strong. To put it another way, the stronger it was, the more heroic maneuvers could be achieved without breaking it. The ability to perform such maneuvers made the survival of Izzy more likely, and so requests for additional structural work had a kind of self-justifying force. Conversely, a weaker structure limited maneuvering ability and increased the odds that they would have to jettison the Mining Colony in order to survive. And why dump scarce resources into beefing up a subassembly that was going to be abandoned anyway? A similar dynamic obtained in the case of propellant. More of it was needed to maneuver an Izzy with a big rock on it, which meant less of it for the arklets, limiting their autonomy and operating range. Thus physics drove politics to the extremes of "ditch the rock now" or "keep the rock at all costs."
