I was referring to their last line ("I will never be able to simultaneously experience the productivity of i3 and the necessary evil of MS Office/Illustrator on the same OS") not the linked article because the parent doesn't "think that this will solve spaces on MacOS" therefore I gave a suggestion that would.
Secondly I don't find anything that bad about why the article's author doesn't want to use yabai, I generally disable SIP anyway (because I want to install anything I want without restriction, even edit system files because that's necessary in some cases, as yabai does); and they just don't want to learn a new WM which is fine for them but isn't a valid reason for everyone to not use yabai.
