NASA'S MANAGEMENT OF THE ARTEMIS MISSIONS.

"SLS/Orion Production and Operating Costs Will Average Over $4 Billion Per Launch [...] We project the cost to fly a single SLS/Orion system through at least Artemis IV to be $4.1 billion per launch at a cadence of approximately one mission per year. Building and launching one Orion capsule costs approximately $1 billion, with an additional $300 million for the Service Module supplied by the ESA [...] In addition, we estimate the single-use SLS will cost $2.2 billion to produce, including two rocket stages, two solid rocket boosters, four RS-25 engines, and two stage adapters.

As per your second link; https://www.wsj.com/articles/elon-musk-expects-spacex-to-spend-around-2-billion-on-starship-rocket-this-year-31f768fb

Elon's spent only 5 Billion on the development of 10 bllion budget, for which 3 Billion is dedicated to the fabrication and population of the Starbase factory/town.

Which then if we take the 2 Bil that was actually used to develop Starship thus far, it includes 15 prototypes (8 of 16 have survived) as well as two stacked ships for a total of 18, means that each prototype has been roughly worth 120 mil plus or minus.

So right now we have 2-4 Billion dollar single launch asset, or we have a prototype asset which has gone through nearly 20 iterations for the same price.
