Andrew, you're missing the point that most of Earth's imports and exports would be in the form of "Information, Arts and Literature".
Movies, books, some types of art and new Songs can be sold as data streams.
Physical goods are usually too expensive to ship to another solar system, even using Hyperspace.
Yes, the Luxury trade has been cut off.
The Creative trade, otoh, might be more intense than ever. Artists tend to create amazing things under threat of death.
You'd also have all the opportunistic SOBs lining up to get the "last works" of these people before the end. Some types of "trade" might actually become more profitable than ever.

Yes, I like cats too.
Shall we exchange Recipes?
