im simply trying to understand how it would work in a broad way, therefore i ask broad questions.

from what the world is telling me right now, aggressors of all sizes and intentions will be the biggest threat to a project like this. i will give the linked material a read, but thats really the main point thats sticking for me about it.

is there definition on how society could be organized on a bigger scale, for bigger projects, like what countries are supposed to do today?

i mean, something like space programs need a huge network of different specialized and unspecialized personnel, equipment and materials to work. or the building of education systems, roads or healthcare across the country.

coordination with other nations for even bigger stuff also comes to mind.
