Not to be alarmist, but suppose a galactic federation judges that
humans in their current state of development will pose a danger to
other civilizations when they imminently attain warp capability, so as
a safety precaution they need to be confined to their planet for at
least a millennium. An agent of the federation posing as human
manipulates the population into allowing 100,000 satellites to be
deployed. With that done, federation scientists solve the many-body
problem for the exact necessary speed and trajectory of a small meteor
to shatter one of the satellites such that some of its fragments
precisely target its neighboring satellites, and so on, while the rest
get kicked up into higher orbits. Life goes on but any enterprise that
depends on penetrating the debris field becomes infeasible.
