I think you are making the false dichotomy between a full stack developer working and a full stack developer working well on all three areas. Few people says one person can't do it all. Few people say that nobody can do it. But we specialize in areas for a reason. It takes a lot to be an expect in an area, and multiple that by three and its even more work and time. So sure, one person can do it all. Sure, one person can do it all well. But the later is much rarer than the former. And have specialized people for each area who can focus exclusively on their area is better.
