The alternative in other languages is the error (using a socket that has been closed/resource that has been semantically moved away) is only found at runtime. The compiler flagging a mistake like this exactly the point of having the compiler and is a great example of how Rust helps defend against mistakes. Compiling early and compiling often is a great way to develop, IME.
In Rust, I personally don't think about moving vs. not until the compiler tells me I have to, because it usually doesn't matter. Rust previously required moves to be explicitly marked, but it wasn't worth it in practice: http://smallcultfollowing.com/babysteps/blog/2012/10/01/move... (see "Wait, doesn’t this make it hard to know what your program does?" in particular.)
