I would really enjoy being able to do mail runs. It is good framework for "story bits" and could be a nice break from the heavier work. As I've gathered one can do some deliveries to stations (new to the game so ignorant of features) and to me deliveries of
mail and even passengers is something I would really enjoy. It might be hard to make this an challenge, but the the lowly postman is seldom greatly rewarded, they just provide the glue of civilization that's all. No need for any deep content even, Id be satisfied with "milkruns" as a way to familiarize oneself with the world. Any "traversal" challenges is something I enjoy after playing Witch Strandings, so having a route, and clearing it over time like an ice breaker is also 👍 to me.
A ship suited to this could be small and cheap and a way to "recover" if you really messed up and needed to sell the mining barge, but now I'm putting ice on the space cake. (Biomass and bacteria cultures is also something I envision would be needed to be regularly supplied to habitats, and one could maybe "break sieges" and smuggle biomatter to autonom-habs. And to be crude even "relieve" some habs of the more fecal biomatter, and deliver it to a farming installation) Edit: yt was no
But unless someone can give a [fancy science-] reason for some areas of the belt being unsuitable/ too wild for astrogating, my quickfix would be to say that the parcels📦 (mail makes no sense, Morse out some lidar stuff or use the 📻 like everyone else ) are to fragile for the 'gating somehow. Nah, that makes no sense either, all the qaint old timey jobs can be automated away, no reason a manual delivery would be better than some algorithm. Could the recepients be afraid to be picked up by "the system" somhow, or be flooding it's zone with some disruptive field, necessitating a lo-fi, transponders off aproach? stumped right now. edit: spelling
