There’s not a lot Elon can actually do in that scenario since they are reliant on NASA and the US government letting them launch to do so. Private space flight is another story, but SpaceX has only started doing manned flights somewhat recently so I actually do think they would do the right thing in that scenario because no one is going to fly on a rocket that they think will kill them.

Also remember that SpaceX has been gung ho about testing in ways that don’t risk anything other than the vehicle, like the Starship test flights they did earlier and failing to land the booster stage of the F9 thousands of times before doing it consistently. It took a long time before they started flying people on the Falcon 9 and we’re not going to see Starship fly people for years.
