It makes the meaning of "meaning" self-referential. Usually, when we say that something has meaning, we mean it is significant to something external to it. If the most external thing at all does not consider our existence significant, then "meaning" becomes entirely subjective: something is defined to have meaning if we convince ourselves it does. Some may think that's not much. Others think that if that's as far as we can go, then that is everything.
I am not sure I understand what it is you're saying, but sure, for many people something is meaningful if it is significant to other people, or even themselves. Others find that less satisfying, requiring a more absolute meaning.
