Usually the problem is that new users go out of their way to fuck things up.

I don't see anything wrong with that. Most of us did that and that's how we learned. But really, all mainstream distros are good out of the box unless you have an unusual hardware configuration. Specially now with flatpaks, appimages and Snaps.

Of course if you want to tweak and twist KDE or install extensions on Gnome or PPAs from who know where on Ubuntu or overuse the AUR in arch you need to know what you are doing.

However, it's no different in Windows but for different reasons. The most common way to fuck windows up is to start installing software from non reputable sources. I think many of us have had to clean windows installations from friends and family when it becomes unusable.
