Who would pay for a space-rescue network?

Who would pay for rescue refuges that make future space travel safer?

The case offered is for pooled public funding, because the network's shared benefits would not justify building it for one individual's use.

The refuge proposal raises a separate funding question because a traveller would benefit from stations across a wide area. The case for public funding is that no individual would gain enough personal benefit to build the whole network. Pooling resources could support infrastructure with benefits spread across the economy. The argument ties those spending choices to the policies voters support and the limits imposed by political opposition.
