I hope they have the whole thing super-practiced and can do one per week like a big production line.

Big planes, which are of similar complexity, have production lines rolling off one per day, so it's doable with the right processes.

Big planes have an order of magnitude lower complexity than a rocket of the Falcon 9's caliber. That's a somewhat subjective statement, I'm sure, but even if it weren't the case there's so much variation between each Falcon 9 I'd be surprised if they could crank that many out with any reasonable amount of QA.

The Soviet Union managed to produce their Soyuz-U rockets at a higher pace than that some four decades ago [1] while achieving a success rate of > 97%. Sure, it's a different rocket with different capabilities, but it was also a long time ago.

Big planes generally have better failure modes as well, and humanity has more experience in producing/operating planes than rockets.

...one only has to make a similar comparison between Tesla and a variety of auto manufacturing firms to note there is a distinct whiff of under-performance and delays that, by outward appearances, appear to be top-down culturally.
