90% will be tanker launches, and will be reused. If one fails, you just launch the next one coming out from the Starship assembly line instead of reusing.

On the contrary, I'm convinced weight can (ab)solve many sins. The JWST's solar shade would have been much less difficult to develop if it wasn't so weight constrained. > Everything's easy in space until it has to
