The question is how much of that cost was involved in getting it to fit the launch constraints? The materials chosen, the unfolding method, etc. On top of all of that, it has to be made so that it absolutely cannot fail. Imagine instead launching components that could be docked together in orbit, tested, and then boosted to it's destination orbit.
