NASA does a lot more than space launches, and they do use private sector (including SpaceX) for most of their launches.
I couldn't find a comparison of the number of launch failures between the two, my recollection is that this happened a lot more often in SpaceX rockets. But maybe that's included in the cost overrun figures and still puts SpaceX ahead by an order of magnitude.
I agree with the thesis of the paper, that platforms and incremental advances are more efficient and more economical. I don't quite agree that an incremental approach would have worked well for the NASA efforts in the 60s and 70s. Perhaps it should be considered as an option for these large organizations, but I'm not convinced it's always better.
Also, to do this study fairly, you would have to set up SpaceX to not benefit from any of the advances made by NASA for the decades beforehand. Some step-function style advances did happen under NASA supervision that benefitted the entire scientific community.
Also, if you're doing a fair comparison between public and private sector you've got to consider all the launch startups that aren't SpaceX, including the ones that haven't successfully launched...
How is that working out with the US Health Care System?
In both cases, I don't think the system works well without assuming spherical cows or something like that.
Edit: ah, I see it's "hurtling." Although I guess in both cases you have to dodge larger and larger geographic regions to claim success, so a bit like hurdling. :)
Great system...
