You don't throw a book away because it is a physical source of information you (most likely) paid for, that you can access even without a computer. You can't just "download" it again in a few minutes should you throw it away, because it's not digital. Same goes for a physical manga, but not with anime or digital manga.
I don't see why you would hoard every single anime you've ever watched and every manga you've ever read. I'd understand keeping a file listing all the ones you've liked, but storing them seems like a waste of HDD space to me. You can always get them from somewhere on the web anyway. Don't give me the "but what if it disappears" bullshit, Japan won't ever purge them from existence, and neither will translation groups, that's for fucking sure.
Unless you're contributing to some online project to archive material for others to use as well, storing anime (or anything digital that you don't have a strong attachment to for that matter) doesn't make sense because it's the exact same TV show/mango you've seen before, and you already know how it goes down. Nothing new will be gained from keeping it when you could use the space for other things, and if you eventually get the urge to go through it again, just look it up online. I mean, how many times can you watch the same show over and over until it gets stale? Odds are you already got all the reaction screencaps you would ever want from your first viewing anyway.
Besides, even if it somehow does disappear, you've already seen it anyway. I don't see the point.
