I guess i've already written about the automation part based on subtractive

manufacturing. Those things, whether the space escalator or the buildings,

can be targeted automation per step. Not all of it, it would still need

people. But can be reduced.

 

If laser is impratical, then, machines designed to be easily replaced

cutting and drilling, its end bits in contact with the minerals must

become modular. Easily installed.

 

Which would require metal compression/folding tools, to increase its

density, and maybe some minerals from Earth to create an alloy,

as well as casting.

 

I think, to call it truly 'colonized' by humans is to use their

own resource with these 'create something from nothing' type of tools.

 

Lasers can be useful in a very mineral collected environment

where it is mostly rocky surface. But maybe unnecessary.

 

So yes, there are impractical parts to my plans, but it can easily

be adapted and changed. I suggested these ideas expecting these changes.

 

But what it aims for, and how it gets there is inevitable.

For we've already tested it on Earth.

 

The order and usage is a matter of choice I think,

and limitations only in automation.
