> Static member functions are tied to the class while virtual member functions are tied to the object.
That's nice, but the entire point is, that the caller doesn't know the type of the object, it only has a supertype. That's why you need dynamic dispatch here. Of course you can implement dynamic dispatch without function pointers, but it is done with function pointers here. If you don't want to name dynamic dispatch implemented with function pointers a vtable, OK, that's fine, but that's the definition I am familiar with.
