In a less mechanical sense, why should your Wizard (who, if you're playing from 1st level, probably started doing this whole "magic" thing less than a decade or two ago) have access to magic that is as good, if not better, than someone who literally turned themselves into an immortal skeleton so that they could study magic forever?
