Without used games the industry will shrink. There are plenty of games I would not have bought new if I didn't have the option to sell them later when they don't turn out to be all that great. Plus I can buy more new games thanks to trade-ins of those non-keepers.
Now you can argue I could just wait for them to go on sale on Steam. Yet I've only seen my wishlist backlog grow over the years and never actually buy them when on sale. Too much new stuff to play all the time, and I've stopped hoarding Steam games before it got out of hand.
My Steam library sucks anyway, all my good games are physical. My Steam library is diluted with bundle deals and stuff that I never want to play again. My physical game collection is a wall of great memories.
