Why does selling a thing give less money than buying a thing of the same value?

I think it's pretty well balanced. Firstly, what does one usually buy? Things that you can't make, eg neutroamine, lances, glitterworld meds, etc. and important resources like steel and components. There may be some nice early game purchases like a sniper rifle or meds that you can't make on your own yet. Now, what can you sell? Garbage, and lots of it. While you wouldn't buy junk weapons and lots of random leathers, you certainly can sell it. Selling garbage plus art, drugs, or whatever will easily keep you in increasing silver even when being a bit free with the spending. Generally the stuff you need to buy is different than the stuff you sell so it works out overall.
