You're welcome to believe that. Visible progress to date suggests otherwise to me; I pretty much ignore what Elon says as much as possible. Besides, however ridiculous, 15 full stacks would still be cheaper than a single SLS launch in all likelihood.
Even if I'm wrong, though, it wouldn't invalidate the point I'm making in this thread: BO's Mk2 has the exact same issues in a more complex architecture.
