There are a couple of problems with this in my experience. People who have done computer science or systems/OS programming in a lower level language like C are really comfortable with concepts like pointers/references/links, objects, trees etc. But there are loads of programmers who don't speak this language at all. When I try to explain that almost everything is immutable and append-only and they are only mutating a single reference called HEAD it just doesn't make sense.
The other thing is, like you say, git itself is a terrible way to learn these concepts. A command line interface is great for expressing operations, but the state, before and after, is basically invisible. I think this might be especially hard for more visual people. When I was learning data structures drawing them out and "seeing" the structure was vitally important and I know it's not just me because computer science books are filled with pictures.
I really want there to be a GUI I can recommend people to use for git, but I'm not aware of a good one. I use magit which helps a lot, but I can't recommend that to most people. All the other GUIs I've seen are just about doing command line stuff with a mouse.
