Java has `sun.misc.Unsafe`, and Python has the FFI which is remarkably easy to misuse. The point is that you don't use these unless you need to, and you spend special effort when you do - same as `unsafe` in Rust. The rest of your code runs perfectly safely, and the vast majority of code has no need to use `unsafe`. Code which uses `unsafe` and isn't obviously either directly an FFI wrapper or a straightforward implementation of a generic data structure is generally considered bad form.
