Variable in rust is not a label you can pass around and reuse freely. It's a fixed size physical memory that values can be moved into or moved out of. Once you understand that everything makes sense. The move semantics, cloning, borrowing, Sized, impl. Every language design element of rust is a direct consequence of that. It's the values that get created, destroyed and moved around and variables are actual first-class places to keep them with their own identity separate from values that occupy them. It's hard to notice this because Rust does a lot to pretend it's a "normal" language to draw people in. But for anyone with experience in programming that attempts to learn Rust I think this realization could make the process at least few times easier.
It's hard to shift to this new paradigm and embrace it, so in the meantime feel use a lot of Rc<> and cloning if you just need to bang out some programs like you would in any other mainstream language.
