Not only is he wrong that it doesn't impact him, because VTI is impacted, but the whole premise is wrong. "I'm not harmed" does not mean things are fine. If I go murder your neighbor, will you come to my trial and demand I go free because you weren't harmed? Should the judge let me go because he wasn't harmed?
He wasn't making the case he isn't harmed. He was making the case that the effect isn't large. You don't appear to understand the claim itself, let alone the reasoning.
Just because you don't understand the basics of the financial system, or the different indices, or the amount of money flowing into the funds that track each, it doesn't mean others don't. The impact if it had been included in the S&P500 would have been at least an order of magnitude more than just the nasdaq 100.
