I hoard media I'll watch later. It's useful to me because I actually do watch it. I tend to rewatch things more often than I try new things so my goal was to basically have 14 TB of media to watch anything I could ever want then stop there. But.. There always seems to be something else to do. I downloaded a ton, realized it was bad quality, downloaded better versions, did that process like 3x, then was like "screw it" and downloaded all remux content and encoded x265 with max bitrates to ensure best quality lol. But all this is VERY time consuming and computer intensive. Love the hobby but it's too time consuming and KILLS my hands/eye health (as do most screen hobbies). :/
Edit: currently have around 3 TB remaining on my 12 TB HDD to play with (& it is being backed up). So just downloading until I can't. Stopping before that would prob be wise tbh but cannot get myself to actually stop. It's a hard cycle to break. My PC is always doing something for me (downloading or encoding).
