>Why is it taking so damn long to do anything?

Because it hasn't ever been done before (successfully).

Because the technologies needed to make it all work are still very much in the prototype/development phase.

Because of the potential that if things go wrong, they can go really, really wrong.

And because SpaceX has to keep the bureaucrats on side, informed, and willing to support the efforts. Without an FAA license to launch, there is no launch.
