Then they need to get over that if they want to learn to code
On the one hand I've been using the CLI for my entire career and and would be lost without it. On the other hand also I have colleagues who learnt to code after Visual Basic/Studio became a thing and work entirely in Visual Studio and manage to deliver top quality work year after year without basically ever having to touch the command line, so it certainly doesn't seem to be necessary.
If you really want to learn to program without learning to use the CLI you probably shouldn't pick and OS who's entire development environment is built around using the CLI.
