Yeah, you're right GUI configuration is huge for long-term market share increase for home desktop use. Jokes aside I do use GUI apps/settings mixed with CLI apps/commands, just depends on the situation and my mood, some things I'll use both depending if my hands are on the keyboard or mouse already lol.

Some things I can just not do with GUI personally is Git, package building, or using a package manager, I perfer CLI commands for those things because I find the GUI options less efficient/slower/more annoying. But I feel we do need GUI options for everything so people aren't forced into the command line against their will.

Options are good and in a perfect world you should be able do do anything from a GUI or CLI!
