SpaceX does one thing though... Well, three things. Rocket development, launch services and starlink.
NASA does a whole lot more, they have 10 times as many employees and far more suppliers than SpaceX does. SpaceX is basically a service provider for NASA.
This is kind of like saying that Lockheed Martin is more efficient than the department of defense.
Ok... So what does NASA do that overlaps with SpaceX? Apparently nothing. NASA is 100% dependent on private rockets. Are we supposed to call that a win or a loss?
Definitely more efficient than NASA today. But private companies wouldn't have been able to pull off the moon landing, which was NASA's great accomplishment.
There's a place for government programs and enormous piles of money.
Well one metric would be cost per kg to get something into space. I also recall a lot of people dying when NASA first started going into space, of which SpaceX has not had any rockets explode with people in them, but I'm not impaired enough to make that false equivalence like you did with Mars.
Of course my comment is false equivalence, because the initial assertion is false equivalence.
You can't compare NASA and Spacex because they have different goals. NASA even contract many of their payloads to Spacex, which they wouldn't do if they were in the same business.
