SpaceX can likely build and launch a fully expendable version of Starship for about $100 million. Most of that money is in the booster, with its 33 engines. So once Super Heavy becomes reusable, you can probably cut manufacturing costs down to about $30 million per launch.

This means that, within a year or so, SpaceX will have a rocket that costs about $30 million and lifts 100 to 150 metric tons to low-Earth orbit.

Bluntly, this is absurd.

For fun, we could compare that to some existing rockets. NASA's Space Launch System, for example, can lift up to 95 tons to low-Earth orbit. That's nearly as much as Starship. But it costs $2.2 billion per launch, plus additional ground systems fees. So it's almost a factor of 100 times more expensive for less throw weight. Also, the SLS rocket can fly once per year at most.

The starship is built out in the open, the whole world can watch. Because of that, there are pretty good estimates for how much construction costs. If you take the more pessimistic estimates, my statement would still hold true.

Also, as a reminder, even without knowing exact numbers you can still make some ballpark assertions with confidence. For example, Jupiter has the mass of more than a dozens earths. I could look up the actual number, but I can be pretty damn sure it's more than twelve.
