I think once SpaceX gets big, he will get so focused on milestones that if he loses some astronauts and gets sued for damages, he's likely to leverage everything he has for more flights. No matter how safe those ships are, they're not infallible, so while it may be a safe bet it's not a guaranteed bet. If another crashes after that, or he loses contracts, he could be filing for bankruptcy, and taking Tesla down with him.
