If you're able to horde in a healthy way it's no problem. I just think for a lot of people it tends to become an unhealthy obsession of relying on obtaining media to self medicate. Chasing the dragon trying to obtain more and more media. Then ultimately facing the disappointment when it doesn't provide the dopamine fix or childhood nostalgia you're hoping for. I vividly remember the terrible feeling of opening up Plex with countless terabytes of data and realizing nothing here is going to actually make me feel better. Media is a powerful stimulant and I've reached the conclusion for myself at least it has to be used in moderation.
There's a difference between moderation and abstinence, no? If I notice there's nothing I want to watch in my collection or online, I start to ask myself why that is and what unfulfilled needs might be the cause. Then I know I need to deal with that somehow instead of trying to distract myself with a movie.
