Could a first mover lock everyone out of outer space?

According to the excerpt, a Forethought article by Jordan Stone asks whether a first mover could keep others out of outer space. It separates soft lock-out, raising rivals' costs by occupying orbital bands or the best Moon sites, from hard lock-out by force.

Why it matters

The same thing, for different readers.

For lawmakers

Forethought's analysis suggests that rules on orbital data centres and Moon site claims could matter to whether an early lead in space becomes permanent.

The question it raises

The piece asks whether an early advantage in space could be turned into lasting control, a question about concentrated power.

How the finding was reached

In our words, from the source. Weigh the finding by how it was made.

What was done
A scenario analysis by Forethought of soft and hard lock-out strategies for a first mover in the space industry.
What it found
Per the excerpt, a first mover could plausibly make a comparable presence in space about $49-73B more expensive, roughly 5-7% on a build of about $1 trillion; soft lock-out falls far short of excluding later entrants.
What it does not show
The excerpt is cut off before the discussion of hard lock-out and the authors' stated caveats.
