If SpaceX uses it's Starship as the primary vehicle and it's F9 as a secondary vehicle, could they not be utilized by NASA as two separate launch providers? If they maintain the F9 infrastructure and have a separate team that operates them apart from the Starship, couldn't they be treated as different launch providers within the same company and thereby provide access as a primary and secondary launch provider to NASA, thereby providing assured access?Is there anything that states explicitly that launch providers must come from another company?
