The user is never be expected to type a command into a terminal.
Nope! Absolutely not. This is where Windows 95 fucked us all over. Prior to 95, windows was an application executed from a DOS prompt. Users may not have known many commands, but they learned that commands could be given.
Windows 95 tried to convince us that a GUI developer knew better than the user everything the user wanted to be able to do with that computer. It did make simple use easier, but the way it did it was by hiding the average user away from any simple ability to automate. It took away virtually all command line utilities that could be scripted to run themselves, and replaced them with GUI-driven applications that required the human's time and attention, repeatedly and monotonously sorting through graphical menus and prompts to achieve a task that the computer could easily be "trained" to do itself. It did it by dumbing down the user, reducing their expectations to the few idea the GUI allowed them to express.
GUIs are Fisher-Price toys. They are the bright and shiny, but functionally crippled. There is no need for a distro that deliberately impairs the user in the way that you describe.
