In the year 21XX, Earth sends several slower-than-light ships to colonize Earth-like planets. The atmosphere, topsoil mineral composition, and the frequency profile and intensity of light on these planets are similar to those of Earth. The ships carry colonists and terraforming biosphere kits that would explosively populate a region of a new planet with Earth flora and fauna (destroying native flora and fauna, if any) and make it fit to support a late 20th century human civilization.
Centuries later, the Earth is a Future Earth as seen in Golden Age sci-fi, relatively peaceful after another world war, with no virtual reality or transhumanism. Earth humans discover faster-than-light travel and establish limited contact with one such colony world.
The colonial civilization there fell to a pre-Industrial level soon after landfall for various catastrophic (non-systemic) reasons but is stable and developing at a "normal" historical-Earth rate. There's also native flora and fauna in the non-terraformed part of the planet, but no non-human sapient life (as far as anyone can tell). Native life and Earth life can't interbreed.
What might Earth humans want from this society, economically?
The Earth project team has split into several factions along ideological lines. Collectively, they've agreed to respect the human rights of the colonists, their political organization, and their sovereignty over the terraformed part of the planet. Nothing impedes Earth humans from landing in an unoccupied, non-terraformed area and mining the planet for mineral resources if they feel so inclined.
