What is wrong with this POV is that the original class no longer has a word to say if she wants to be friended by someone.
In C++ the class has a word to say: if it does not declare: "hey! you will be my friend!", then nobody can come there to say: "hey! I consider myself your friend (even if you don't want it), so I will mess up your internal state!"
