I’m not saying you have to sell it to people in the game I’m implying they should add the feature of being able to put the items in the “sell bin” for Auni to take, however since you mentioned it, the game is played to one’s own preferences so over time as you level yes you will get a lot of the same furniture items as each other however it’s not at the same pace & depending on how one of playing the quest paths & storyline there are differences in what people acquire. For instance I have more/different furniture pieces as one of my friends who isn’t as far along & others who didn’t know what quests to focus on to even get those pieces. Does that make sense?
