 The Long Night is an ENTIRELY
 different scenario than what we were discussing. When Route
 66 was supplanted by the interstate system trade didn’t
 cease; it merely bypassed certain areas.

 Under the pressures of the Long Night, any
 system that wanted or needed to build a jump drive could
 have put forth the effort.

 Being TL8 in the Imperium (1st, 2nd or 3rd)
 doesn’t mean ‘We don’t know Jump Drive exists or how
 to build it’; it means ‘We don’t have a Jump Drive
 factory in our system’. Now low-Pop TL8 world may not have
 that capability, but Pop9? certainly.

 It might be difficult and/or very expensive to
 build such a drive, but the knowledge is there, almost
 certainly. By the time of the Long Night, Jump Drive had
 been in use for MILLENNIA. The knowledge wasn’t lost. If
 NYC was suddenly cut off from the outside world, they
 wouldn’t forget how to make steel; it would just be
 expensive to build a plant from scratch.

 The Long Night also didn’t mean that all
 interstellar trade ceased; it’s just that what there was
 contracted enormously. The Vilani maintained a large
 multi-system trade network the whole time. What wasn’t
 there was a unified government over the entire Imperium.

And yet, still, many worlds were left on their own & did just fine.

Which is the point that I intended to make...

There's just no reason why a system w/ enough pop can't do that.

In fact, a case could be made that a fairly low TL system that still had a large numbers actual living at that level, as can be found in many cases right here on this planet, all the way down to the Bushmen of the Kalahari, could also continue on indefinitely. Of course, those that had become dependant (over-dependant?) upon higher tech than the system could indigenously support would be hurting.
