I'm on the opposite end of consumer habits, I have sold all of my optical discs. If I want to watch/listen something and it's not on Netflix/Spotify, then I just don't. I don't bother with the entertainment that much. Same for PS4, if the game is not available on PSN then I don't play. Changing the mindset from feeling entitled to play/watch/listen something to consuming (or not consuming) things that are on limited number of services helped a lot.
This saves a lot of space near my TV, I just have a simple rack to keep my PS4 there. No shelf or anything else to keep stuff there, also I don't need any big data storage to save my media collections in digital format. I also don't need to spend time to setup my entertainment options, it's either there or not. I recommend this style for everyone.
