C++ users would say that shared_ptr is the idiomatic way to handle this scenario, and it's no more unsafe than Rust is in general use.

Right, but there's a runtime cost associated with it, unlike the borrowed pointer in the rust version. Using shared_ptr is not "toeing the line", it's stepping back from the line in fear you will cross it.
