What can be done about it? Does an alternative internetwork need to be formed? What will it look like? How will we pay for an alternative network? Who will use it?

Obviously you will be intimidated by the government if you run an exit node, or perhaps any tor node at all. If you're an academic with tenure, or independently wealthy go for it.
If you need to work for a living and do not have tenure, well perhaps consider helping others run tor. Or start a non-profit with the goal to promote freedom, and raise funds, and pay to install public tor terminals anywhere that's willing to host them.
