great comment! And you're right, one of the biggest Strengths of Rust is Move done right. With const, borrow, move, ref rules... the default way usually does not make unnecessary copies.
And when you want to make a copy, to escape lifetime annoyances for example, you do a .clone() that very explicit marks a point of a Copy.
