So, two flights to the Moon - ~$4B. SpaceX already spent around that on the developments in Boca Chica, each flight - expendable - is estimated at $0.1B, we already had 4 and they are surely more costly. We still have to have 2 HLS to fly and 20-30 Starship flights to refuel them, and that's the lower bound in expenses.
Big chunk, likely. But definitely not nearly all the money.
That's an interesting cost-based criticism of Starship. I hope you are wrong and SpaceX can actually do this profitably, otherwise its potential will be much reduced.
The development is what already being spent... Each flight, after development is complete, will be reusable - that's the plan - and will cost less than $0.1B == 100 millions dollars, if total per-Starship expenses are divided into the total number of that Starship flights. Yes, I hope the eventual costs per flight would be lower, the point is the cost of the program is surely way more than $4B.
