Interesting figure!

The low gravity is a big advantage though. It is very easy to get things into space from the moon.

So if you can construct things on the moon, you have an advantage in space. It also makes it easy to hurl things into space for more destructive reasons.

I'm pretty sure there are technical barriers to constructing an ore-mining-to-finished-product spaceship factory on the moon.

Sure, many. It's a huge challenge. Not impossible. If we'd set it as goal, we could develop the technology and science as we go. I'm sure humanity is inventive enough. I mean, we did go to the moon with 60's technology...

But even thinking ahead more than 2 years seems impossible these days, everything is focused on the now and short-term profit. Anyway, rant over, it's nice to think big instead of small once in a while :)
