Considering that the keys are not unique per console, it's kind of weird keeping the Switch around just for Yuzu. I mean you can get key dumps online and those work the same since they're all identical.
Only real reason to do it is because Yuzu devs said so, and that's not a great reason because they don't have any authority to say so, nor any way of knowing if people are actually doing that.
You can usually find it by googling or searching for "prod.keys for yuzu" and you'll find links. Beware of scams though, only download the prod.keys and title.keys, don't use pre-packaged emulators from these sources, only use the official ones with the keys from them.
I got a link from a friend here on lemmy that looks to contain everything needed to use Yuzu (emulator/keys/firmware and mod stuff). Haven't had a chance to test it out yet, but it looks to be complete.
Ah, the pains of emulation. It took a long time for Dolphin(Gamecube) to be usable. I always thought modern consoles had less hardware quirks and were more "plug and play" than consoles of yesteryear. And that emulating them would be easier.
I guess I was wrong.
I have a Ryzen 5600G (with Radeon Graphics built in) and 16 GiB of RAM, and it runs fine (with a few hiccups during cutscenes). I'm also running Linux, though.
