> In order to have a reasonably complete language that has RAII and value types, you must also have: - constructors - destructors - overloadable copy assignment operators - placement new - move semantics and rvalue references

C++ didn't have move semantics at all until several decades after it had RAII.

Yes, move semantics were added because the language was considered incomplete without them. In particular, because RAII based resources like std::vector could not be relocated without very expensive value copy operations.
