Uhm - most names have a meaning even if we don't really consider it nowadays - like Alex (short for Alexander) comes from the Greek Alexandros meaning "defending men," from alexein "to ward off, keep off, turn (something) away, defend, protect" + anēr (genitive andros) "man" (from PIE root *ner- (2) "man") - so most names have a meaning - and you could argue that over time pronouns will lose their meaning like names and will just be a shorthand for self-identification - but I don't see how that's any worse/different
