A big part of preservation is curation. Even libraries throw away books that nobody lends for a certain amount of time. They have limited shelf space so they need to curate the collection periodically. Same with digital collections. Yes, it's easier to extend the space available, but it's still just hoarding unless you curate. Case in point: You can easily get every single Gameboy game for every Gameboy variant. BUT. You'll get _every single Gameboy game for every Gameboy variant_. That's thousands of games, in multiple languages and minor version variants. You'll also get rom hacked versions with different cheats enabled for the games. It's an immense pile of crap you (or someone) need to curate by hand to make it an actual collection of games. Going through your memories and multiple reviews checking which games are actually worth conserving and which were just shovelware is a ton of work.
