It doesn't hurt but I just think the other person was exaggerating how difficult the process is if you aren't doing anything unusual that a random forum said is the best way. If someone has trouble installing Linux, they would probably also have trouble installing Windows from scratch.

It's just that most people don't usually have to do it themselves. That's a general lack of computing knowledge/skills that will always be a barrier and can't be solved no matter how easy Linux gets for the average person to use. It requires that person to gain more familiarity with computers in general.

Which is different than the difficulty of having general computing knowledge, but not understanding the difference in workflow. Such as installing an app from a store like KDE's Discover instead of from the website directly or from the Microsoft store, which would be the closest analog but not as common. That's where I think most of the difficulty comes in but that can also be worked on by distros to help overcome.
