That's certainly valid. I've had friends throughout the years that used vim as you would nano. I don't think vim is any good when you use it like that since the more advanced features just get in your way, but if it works for you then that's cool.

The people who seek out a "learn vim" course are just not that kind of people. In this case you've signed up for a course on how to speak Spanish only to ask the teacher to not speak Spanish.
