if you care about anyone who says you are stingy or materialistic ,you either do not have confidence in yourself or people who know you or
you have too much time to care for these comments.

You have missed the point that loved ones are typically those we trust most. When they betray that trust by making false accusations that damage our reputation, it can cause significant emotional distress. It has nothing to do with the lack of confidence of the wrongly accused party.
