You'd be missing the whole point too if you think that the pointer is the root cause. The problem is that the class is not designed to be copy-able, let alone moveable. Your suggestion to use a unique_ptr will also blow up in your face the moment you try to copy an instance.

Depends on what semantic you want. Sure, if you use a unique_ptr member, you will get a deleted copy constructor/operator - I wouldn't consider that blowing up in my face.
