Because what we have works well enough for the task at hand. The problem, which Stephenson alludes do earlier in the article, is space just isn't proving to be as useful as we had anticipated. We're already doing pretty much everything that you can justify from an economic perspective. Activities like asteroid mining and space solar power aren't going to make sense for centuries even if we dramatically cut the cost of $/kg to orbit.
So sure, we could do the same things more cheaply after a huge investment in, say, tethers. But so what? How does it make sense to spend trillions on a new launch technology when you could use that money to buy all the conventional rockets you'll need for the next 50 years.
