It's quite interesting how you're completely unwilling to argue the original point (which is that a 1860s construction project is no model for today as it came at a great cost we're not willing to accept, besides being completely incomparable to the modern-day example you gave), but completely willing to argue quite meaningless aspects to the discussion seemingly for the sake of it.
