I'm sure there could be better rocket configurations than Starship - but so far Starship is better than other existing schemas. Starship is really good comparing to others - getting the cheapest kilogram to orbit cost in perspective.
> As I said in my other comments, just cause something is sold at a lower cost doesn't mean its optimal.
No, Starship isn't optimal, it's just better than existing alternative by this specific criteria. If you need some other quality, you may rationally choose something else.
The point was that the price of kilogram to orbit is an important criteria for many customers, so they logically choose Starship.
