concreting in space

But launch costs from the moon would be also more than launch costs
from an asteroid since the asteroid has only micro gravitation. But the moon is much closer to the markets in near-Earth space. Travel times are days rather than months. But don't get me wrong, I'm not arguing that lunar resources are superior to asteroidal. I would only argue that each scenario have advantages and disadvantages. I wouldn't even place bets on which will happen first, but I think one way or another, both will happen.
