All of fiction and discourse fails to consider that the Solar System is actually a huge place and just the period of settling and industrialising it will take hundreds of years.

Everyone things that a game breaker technology is better engines, or fusion, or FTL, but they are wrong, the game breaker technology has already happened: 3D printing.

If we can manufacture things with minimal infrastructure using local resources, we can that is all we need.

And all of it reachable with simple nuclear power and technology we have today.
