Economics (was Critical time)

If what you say is correct, then this is most depressing, because it
implies that there is essentially no way a private entity could ever
justify using extra-terrestrial resources.

...Whenever I mention lunar mass drivers, or use of lunar resources in HEO,
it's always in the context of a massive SPS construction program, and/or
orbital habitat program. In those cases, launches from the moon will
increase. But I'll be the first to agree that use of lunar ores makes
little sense in any operation much smaller than this.
