Yes, it just requires the initial investment to be able to afford a cargo full of them. There are places where you can do a two-way trip between two systems, e.g., superconductors in one direction and progenitor cells in the other, each yielding around 1K per ton. And after a few runs you can afford a bigger ship, then repeat with even more profit per run. Of course it gets boring at some point (and after a few IRL days these routes usually become less profitable and you need to find a new one)…

Also, don't rely on a juicy trade route you have worked out when Gamma is released. Going by what happened to different planetary systems between Beta 1 and 2 and Beta 2 and 3 the planets will be randomized (except the hand crafted ones) again.
