"Worthless in practice" . . . not in my experience. Many leaks occur as people cut-and-paste or include more and more people in casual distribution ("Hey Joe, you might be interested in..."). Putting restrictions on a document helps this.
Security is a process, not a destination. Guarding against casual or thoughtless disclosure is a great mitigation; don't dismiss it because it doesn't solve the whole problem. No single thing will.
