Linux is easier if you’re already comfortable with a computer. A lot of users wouldn’t understand how to edit a config file / would be uncomfortable doing so, especially those who grew up with modern phones and apps. Even if a 30 second edit took 30 minutes in a GUI, lots of people will prefer the GUI.
Unfortunately most people find Windows / MacOS “just works”. If Linux was that easy, adoption would be higher. I love my Arch setup but the average user would probably find it unusable LOL
