I disagree 100% with this. The crossbow in this game is over 20k to buy.... You need every penny you can get. Later on you might be rolling in huge amounts of money because you can sell all that high end gear, but if it costs you that much to buy things, then you must be able to sell them at a fairly high price, as well.
To be fair, the entire economy of the game is borked (just as it was in warband). There is one currency amount (the gold coin, or whatever) and there is no sense of value in things, the prices of equipment is all over the place.
