Ask yourself why a company that has hundreds of launches under its belt thought that delivering 6million kg of thrust to a concrete platform, with nothing but a shower of water to diffuse that power, would not disintegrate the launch pad and scatter the debris far and wide and why they would not anticipate that at least some of that debris would be blown in the direction of the ship itself and damage the engines during take-off, as it most obviously did.
I think the answer is cost-cutting or complete stupidity. If you can plan a trajectory to Mars and beyond, but cannot anticipate the trajectory of a large amount of concrete scatteting during the 'unscheduled disassembly' of the launch pad, then should you be launching at all?
Personally, I love the Starship, the concept and the sheer audacity of it and I can see the advantages that it could give us, the teflon pan buying public, but if someone thinks they can put a bomb under a spaceship and not expect or plan for the kind of debris we all saw, then I'm not sure I'd want to book a flight with them until someone else was in charge of health and safety.
