Using an Oxford analysis between SpaceX and NASA isn't the bolstering claim you think it is. NASA's bread-and-butter is innovating new nonexistent technology, and is hampered by political interests of Congress. While SpaceX's replication of already existent technology (that wouldn't exist without Public Funding and decades of work and research by NASA footing the upstart cost) is to be commended, their ability to innovate is nothing short of a disaster. "Failure is not an option" has been replaced with "well, it cleared the tower before it blew up!" level incompetence.
No privatization generally means less-quality and less public control, which means less sense of community and less caring. Not to mention, NASA isn't actually saving that much money using SpaceX when compared to when it ran the SpaceShuttle in terms of the payloads themselves. There's a lot of bad reporting out there (that doesn't do the math they just take the reports of a private company with unopened books as gospel), and SpaceX is burning through investment cash...which demonstrates it's not running profitably (so it's all an illusion).
