"Figuring out how to launch stuff extremely cheaply" is not some kind of secret sauce or competitive strategy, it's literally what every rocket company is also working towards. The ability to specifically target Mars risks optimizing for a rocket that is extremely wasteful relative to what the market is willing to bear. Case in point, what companies want is not shipping material on Mars, the moon, or any deep space capability; they want satellites in Earth orbit. You don't need Starship for that, instead you need to double down on Falcon, and every dollar spent on the former is a dollar that's not spent on the latter.
