This is also a documented statistical fact - more than 90% of Yuzu users (or emulation users) do not dump their own keys. That, kind with TOTK famously getting pirated over a million times before release; shows that most arguments about morality and preservation of culture (although they have merit) are mainly given by people interested in justifying their own actions.
Of course they don't, this isn't some big gotcha. Why even bother when a Google search saves you the work? I play some old Pokémon games that came out on the DS and ya know what, I just downloaded the game and shoved it in an emulator rather then figuring out how to get it out of my own cart.
Some nice person already did the work and I don't feel the need to conduct legal ritual with candles and blood rites to get a blessed copy of the same damn bits that are just sitting right there. If I could just get an Nintendo SD card adapter and plug it in to my laptop and dd to get the image it would be a different story.
