Why isn't operator overloading for pointers allowed to work?

Question

As per the comment under this answer, references were introduced primarily to support operator overloading which quotes Bjarne Stroustrup:

Answer 1

It's 2019 and you still do not have access to the classes of native types. There is no way to override operators on them.

Pointers are (like char, int, float, etc...) a native type. You can create an object that behaves like a pointer and overload operators [->, *], but that will not overload [->, *] on the the native pointer. You may also, for example, create an object that behaves like an int and overload [+, -, *, /], but that will not overload [+, -, *, /] on the native int.

For pragmatic rational, imagine the chaos if

this->member

had user-defined meaning.

References are an unrelated topic, IMHO.
