That may be true, but if you're one of the many people who will never be able make serious use of the train, or you're one of the businesses that had to close shop or move due to eminent domain of the project, or worse yet, you're one of the businesses mentioned in this article and you go bankrupt due to the impact of construction, your only option is continue forking over your tax dollars.  If they don't like it they can go pound sand.
But no worries, it's all for the greater good.  And to paraphrase all great socialist projects, "You can't make a an omelette without breaking a few eggs."  Aloha!!!
