You're assuming everyone is coming to Rust from C. People who are learning Rust from a garbage-collected language will absolutely feel that Rust is harder than what they're used to, and not because they were writing bug-ridden code in Java or whatever.
Single ownership often introduces bugs of its own. In Java, I never need to create an Err if the thing my ID is "pointing" to isn't around anymore in whatever hash map the borrow checker made me store it in.
