Yes, I can correct you. 100% of the cost would be labor. The materials are stone, it's free for the taking. Paying for the blocks and transport is paying someone to get stones from where they sit, shape them, and transport them. A billion dollars would be dirt cheap, may as well be free at that price. I'd guess a full trillion.
