I’m not sure you understand the arguments being made here. $1m per launch for F9 is ludicrous because 20% of the rocket, by manufacturing cost, is expended on every launch. For Starship none of the rocket is expended per launch, the only costs are site operations, fuel and depreciation on the rocket over a hundred or more flights.

They are aiming for daily launches of starship, so the site operations costs would be divided by potentially hundreds of launches per year instead of the one or two dozen a year nowadays.

The cost model per flight of Starship is more like that of a jumbo jet than that of a Falcon 9.
