why module pattern?

I've read a lot of things about the module pattern. Ok It brings structure, private method, etc... But with the code below I can get the same behavior without using it.

function Human()
{
  // private properties
  var _name='';
  var _age=0;


  // private methods
  function created()
  {
    console.log("Human "+_name+" called");
  };

  // public
  this.setName = function(name){
    _name=name;
    created(); 
  };

}


var h1 = new Human();

h1.setName("John");

So, what are the real advantage of a module pattern finally ?
