I think the reason for some of the misconceptions here is based on the fact that recording music, multi-tracking and mixing...is substantially different from doing a 1-mic narrated podcast, even if both utilize some similar equipment to a degree.
I can understand why in a podcast you would kinda "set-n-forget"....which is not unlike a typical radio broadcast. There's no involved tracking or mixing going on there.
I mean, there's even not much consideration for multiple mics, multiple sources, and all kinds of levels to deal with...
...but when you're actually recording music in a typical studio environment, there's few occasions where you would just line up your mixer faders at "0"/unity" and then just always go with that.
Not having much exposure to more involved recording usually translates to myopic, singular perspectives, and often "internet knowledge" is just a regurgitation of many Google searches...but that's what you get on the web these days.
So the question here is what's the OP doing...recording a podcast or recording multi-track music?
It's obvious the sources he found on the internet are part of that superficial "internet knowledge", and the OP was right to question it, because it makes little sense in music recording scenarios as some broadband approach.
