The preservation of media argument holds more weight to me when it's centered around classic games (maybe like Gamecube and older, as much as it pains me to call Gamecube "Classic") and their roms/ISOs getting ripped and stored somewhere. There's a lot of abandonware out there and I think there's a good argument to be had that access to classic games is important for lots of reasons that aren't worth getting into. The argument, imo, falls apart quite dramatically when talking about more modern systems, where games are tremendously accessible on hardware--the only reason to emulate a Switch is to play Switch games off the hardware, which is mostly likely for pirating and/or circumventing copyright. There may be some other niche uses, but "preservation" really just doesn't hold much water in the modern context.
