There hasn't been a single failure of a reused falcon 9 booster on launch, which is the bit relevant to human spaceflight. Humans aren't going to ride a falcon 9 down to landing.

If you're talking about starship then I'm not sure how worthwhile extrapolating from F9 is. I would guess they're pushing F9 to its limits here - after all a small gain in launch efficiency multiplied by the size of the StarLink constellation is a big overall improvement!

I'm talking about extrapolating from any rocket launch. Sorry if I'm not clear, but I am talking about starship.
