Why can't constructors be explicitly called while destructors can?

In the following C++ code, I am allowed to explicitly call the destructor but not the constructor. Why is that? Wouldn't be explicit ctor call more expressive and unified with the dtor case?

class X { };

int main() {
  X* x = (X*)::operator new(sizeof(X));
  new (x) X;  // option #1: OK
  x->X();     // option #2: ERROR

  x->~X();
  ::operator delete(x);
}
