I think the technology and learning that will come out of this will be more than worth the cost. It's short sighted to only consider the immediate ROI. A substantial portion of development is also currently being funded by a private citizen (approx $1.5B of the final cost). And honestly, humanity could use a sense of humor sometimes. We spent trillions going to war in just the past 2 decades when we could have spent a couple billion doing seemingly impossible projects like this. Projects like this also provide jobs and have the added benefit of directing our efforts into something far more useful and far less disastrous than something like war.
