Gaiva of any sort, found in a person for any “reason” is nothing more than a deep insecurity. Someone who really knows themself knows their place, and that place is a small part of Hashem’s creation next to the Melech Ha Olam.
When some one is gaivadik they lack self esteem because they lack humility. This is because they lack a proper attitude of being a servant rather than a boss. THey will not feel anything of pride when putting on an expensive gorgeous outfit either, because in knowing that the Aibishter has trusted in their possesion this dress and that He can take it back and they can go to the grave at any moment they will not laud themselves over others.
Believe me – those who seem to have a thing about gaiva because of their Yichus do not really hold themselves high, or else they’d find higher reasons to associate their “highness” on , besides for some good things their dead fathers did once. Like things they have done good in their own life time. WHich by the way, if its a true mitzvah, only really leads to humility and gratitude that Abishter blessed them with the zechus to perform it in the first place.
