Nothing, in the case of OpenStruct, but another class's initialize 
method might do all the work of the object (e.g. create a file, or start 
a process), after which you don't want it any more. You only want to 
access the object _while_ you are configuring it in the initialize 
block, after which #initialize goes off and does something with your 
configuration. But this is a peculiar kind of class. Better design would 
be a class method which yields a config object.
