Why make it harder.

> excellent standard library.

The standard library is intentionally bare-bones. They don't want to maintain libraries in std, and want you to use crates.

> wider ecosystem of libraries

The quality of these is quite poor in a lot of cases. People literally make blog posts into crates.

To achieve static memory safety.

If you don’t need or want that, you’re probably better off sticking to other languages. Although hopefully, not something like C or C++ which the US government now advises against using for security reasons.

As someone coming from C I find the stdlib is fine. It has all the datastructures you need for the vast majority of code. It doesn't have very domain specific things like the kind of structures a text editor might use, for instance. That's fine.

As for the quality of crates, yes, this is the case in any language. Using a library includes the responsibility of making sure the quality is up to scratch. This is not unique to Rust.
