I know insurance for a launch is typical, but seems really tough to do that for this still “rather experimental” launch. I got to imagine it has costs something like 50% on a project like this.

Once Elon showed how to do it, and how cost-efficient it was, a rocket company that doesn't do it is not viable.

The failure of the upper stage is a bummer. If it triggers a months-long review, that will almost certainly bump back the schedule for the prototype Blue Moon lander launch.
