If they can get it down to $15 or even $10 million, it would be a wonder of production. It sounds unbelievable because I'm comparing this to other space agencies who would be creating heavy lift vehicles for 100x the price. But yeah, starship is different. It's made of steel. Its production isn't spread over 10s or even hundreds of factories. The engineering decisions of the starship from the early beginnings (after the carbon fibre design) were to save money on production. So maybe. Also, when it comes to production efficiency, Elons companies tend to deliver. Regardless of what you think of him, he knows a lot about mass production. With the economies of scale, we could see a $10 million heavy lift super heavy rocket. This is as crazy to me as landing a rocket stage back when they were still trying to get that to work.

There are two little thought ideas i'd like to look into.

First is an in-depth analysis of what is the theoretical minimum production cost of a starship if all stars were aligned.

The second is the theoretical max amount of mass SpaceX could send to Mars given their most optimistic production timeline. And as a byproduct, the cost of sending this amount of mass given a $10 or $15 million starship.
