It takes 10 minutes for you.
I know people who struggle to understand that the browser isn't google isn't the internet, try having them install a new OS.
They don't follow the guides, because they don't even understand what they should look for.
Some understand enough but like the convenience, and again that's fair.
Bedsides, gaming distros aren't the mess you say they are, nor are they so much more niche than any other major distro.
Usually they just work, when they don't you look for fixes in the underlying distro community.
You are gatekeeping, and you are condescendingly deciding the best path for everyone else. I get that you honestly think it would be better, still people are different, what's best for you doesn't need to be the best for everyone else.
