What is that based on? NASA's recent accomplishments are far beyond anyone. Off the top of my head: The many Mars missions, JWST, Europa Clipper (still in progress), etc. SpaceX hasn't left Earth orbit, afaik.
That is only looking at (mostly orbital) launch systems, such a minor part of NASA's R&D and missions that the Obama administration decided to contract it out.
NASA doesn't develop or build lots of technology that has become mature enough that private industry can take it on and NASA can focus on the past-the-bleeding-edge stuff.
Reality? Outside of JPL the talent level at Nasa is frankly very poor. You really want to claim that the current version of Nasa could pull off the Apollo program today?
All of which are peanuts compared to Apollo. Not to mention insane cost overruns and timeline failures on their projects like JWST or SLS for example. Many of those successful projects came out of JPL, where I mentioned the talent level is much higher.
