2. Factory Factory builds a factory that builds a solar sail factory

3. Solar sails maneuver on their own power to the Earth-Sun L1 point

I can picture much of the chemical factory involved, it looks something like

https://www.netl.doe.gov/research/Coal/energy-systems/gasifi...

but also something like a conventional petrochemical factory and it probably uses solar concentrators for something. Thin film construction seems possible. There are a lot of problems that are like trying to build a ship in a bottle except you're in the bottle and trying to build a ship outside the bottle.

What has me scratching my head is:

a. Do you have to send humans? If the factory can be started up and run autonomously it saves the need to build a human habitat.

b. What do you do with the volatiles? I think when you punch through the crust of an asteroid you might get a dangerous quantity of gas, which is also highly valuable. You might have to devolatize the asteroid before the metal line and storage tank factory are online.
