There’s always an excess of resources, just in case of spacecraft failure.

There are actually already extra crew up there from the recent Boeing failure.

SpaceX would definitely benefit from having to come get you, since they’re the only launch company with a good track record, and spare capacity. (Unless you’re Russian, which means you’d probably be shot and stuffed in the garbage section of Soyuz)

Compared to telefragging someone on live tv? Also, on the balance, the media coverage would likely help knock loose some more funding for NASA, if only to try and figure out what the f*** happened.

There are always escape capsules onboard so they could probably just set them down to earth if that happens.

I would be more worried about something that is entirely untrained being up there for extended periods of time.
