To the idea that you should be able to get a very minor amount of scrap whenever you find a trade augment.
I really wish the devs had given the ability to use cargo items in blue options and/or remove them from cargo with a command.
That would have made everything so much easier. But unfortunately we just have to find ways around that limitation...
Or at least whenever you get one from a ship as that woukd make writing the text easier. If you don't want the trade augment after helping a ship you could say "Keep it, we're just happy to help" with a chance to get scrap instead. Or as a pirate you could say "We don't want your junk! Pay up or else!" with a guaranteed low payment of scrap.
Some additional ways to sell trade augments for optimal prices would also be nice. For example, when (like in Sid Meier's pirates) drinking at a station the bartender might ask if you're hauling any Cargo (queue Blue Option). If so the bartender could give you the location of someone in that sector who might be willing to pay big for what you're hauling. (Unless you're goods are generic, then they say you should be able to find a buyer for those at any store).
While on the subject of drinking at stations I also think it would be nice if you could maybe get some quests by socializing in the Cantina. It could be an alternate way to start those special quests or get a Bounty Hunter quest etc... It would just be nice to incentivize socializing at the cantina more rather than just choosing to shoot up every station you come across.
EDIT: I had another random idea recently, perhaps it could be possible to get an event to sell your goods by talking to a Slug (or Human even, if you want to make them slightly more useful) crewmember as well. The text could say something like "Your crewmember tells you that they used to be a trader..."(For Slug Gel maybe?
) and they traveled far and wide across the galaxy". If you have any trade augments you can ask your Slug if they know anybody nearby who may be interested in what you are hauling.
