Does Krishna consider Arjuna’s concerns about destruction of family meaningless?

In the first chp of BG Arjuna raises some imp (material) concerns. Destruction of dynasty, family traditions, unwanted population etc. Krishna does not address any of these issues in BG. Does it mean that these concerns were meaningless concerns or does it mean that these concerns actually turned out to be factual, but Krishna was not addressing these issues in his spiritual message to Arjuna?
