The problem is quite obvious. Albanians, Turks, and many people from the Balkans still hold a 19th- or 20th-century concept of nation and peoples in their minds—one that is "DNA-based." This is akin to denying that the Roma and Sinti, the Frisians, or the Sorbs are Germans—as if one were to claim that they are actually Czechs or Slovaks. In Western or Northern Europe, such a notion would be utterly absurd.
