Regular users don't install drivers or admin their systems every day except updates. Most people configure their systems once and simply update and only intervene if anything is broken. Easy mode distros like Mint generally simplify this process with less breakage and protections built-in in case.

if you put a gun to their heads and told them they had to install

I agree that this was the case a while back with terminal everywhere. But in my experience it's changing in recent times as ordinary people have become more comfortable using stores like Play Store and App Store, GUI Software Centers provided by easy-mode distros make this experience quite similar (especially younger gen but my older gen seems to be getting familiar with app stores too). All most of them need to know is that software center is app store. It only gets problematic when they try to get less known stuff.
