The borrow checker is an approximation of an ideal model of managing things. In the general case, the guidelines that the borrow checker establishes are a useful way to structure code (though not necessarily the only way), but sometimes the borrow checker simply doesn't accept code that is logically sound. Rust is statically analyzed with an emphasis on safety, so that is the tradeoff made for Rust.
