Well, the obvious reason is because the Wii has atrocious video output, but yeah, the process is convoluted enough that I dunno if I wanna bother. And you're correct about those upscaling issues.
If that is a problem for you, you could get a Neoya Wii2HDMI plug-in transcoder (NOT a clone though, those have crappy scalers.) so you can convert the multiout to HDMI straight at the source. This way, you have no additional analog signal loss to worry about like when using component cables. Then, you can connect that to your favorite gaming display or scaler, and take it from there.
