Honestly, that sounds like my ideal show. I’ve always wanted a show that gave us something outside of Starfleet, and I’ve also always wanted a show that showed us a little more of earth (cannot wait for a sf academy). A freighter based show could us both. Frequent trips to earth to pick up supplies, space without the protection of the military’s flagship, or the protection of being an important military space station. Tight knit crew, likely family members and all the drama and story that comes with that. God, that would be an awesome show.
