I don't think that lack of MSP or maintenance capacity could be an issue here.
Earth is the Capital with 150,000 ton Maintenance capacity and 102,000 maintenance supplies available. At the current time there is in orbit and under overhaul 2 X GSV ships @ 3,950 tons each and the 2 Mars ships @3,750 tons each , totaling 15,400 tons , way below the capacity. The only other ships around Earth are my commercial Freighters and a Colony ship which do not require supplies or maintenance facilities.
