That’s not exactly how it is right now, but it’s not far. Hell, the last time a F9 booster went splat, they grounded them for only a couple weeks before it was shown it wasn’t a safety-critical issue.
It just stands out because there’s only two flying reusable boosters right now (and only one that can go to orbit). Meanwhile, grounding one model of aircraft doesn’t usually have that much of an impact because they are so many active. What’ll be really cool is when there are so many reusable boosters out there that one can be grounded and spaceflights will just continue on another.
