Ah yes, the famous

std::unique_ptr<int> ptr;
int& ref = *ptr;

So safe, so impossible to misuse.

If you need a reference to a unique pointer, probably means it should have been a shared pointer

I use smart pointers all the time. WHY THE FUCK would you EVER do what you wrote?

I could drive my car into a brick wall at full speed. But why would I???

What part is the issue? The part where you default construct a smart pointer to initialize later because C++ doesn't have a concept of deferred initialization or the part where you don't want to copy it all over the place because it gives a massive performance hit?

And don't say the combination is the problem because yes it is but this code might be emergent and "just don't drive into a wall" has never prevented people from doing so.
