Conversely there's a very good case for arguing that HR is a non-function that should be eliminated entirely as it is almost always detrimental to any organization. The reasons are simple: hiring is best done by those who know what skills are required, not by those who've been passed a job description they don't understand. Legal issues are best handled by the organization's legal team, who will better understand all the ramifications of a decision/action. Corporate culture (whatever that may be) is firmly in the hands of the CEO and a tiny number of influential executives. Training likewise is the responsibility of one's manager who knows what is required for skills development. Which leaves... ordering the donuts for meetings. Which can be done by anyone.
