Mutable data structures are a much more accurate abstraction when it comes to how computers actually store data in memory and on disc Yet programming in imperative, mutating, mainstream languages is nothing like how code works at the machine level. I understand you're talking about data, but I think the analogy still stands. Or maybe a better one is that a file system or even a database itself is an abstraction of how data is stored on disc.
