> Eventually, anti-trust law ... might break that monopoly.

This seems like a weak argument. If you look back to the 1990s, Intel was unbelievably dominant in desktop computing. There was never any discussion that anti-trust law should be used to somehow "break that monopoly". They were just damn good -- way, way better than all of the other competitors. Eventually, Intel's intellectual property pipeline slowed considerably (for a multitude of reasons) and AMD was able to catch-up. And it looks like ARM is biting at the heels of both Intel and AMD.

Tangential: I am surprised that the US gov't isn't paying SpaceX to continue the Falcon 9 programme. That rocket is used a lot to launch US military & spy satellites. Plus, Musk is very patriotic. I suppose there were some private conversations between Musk/Shotwell and senior US gov't officials (military and/or spy).
