			Although the journal/love letter problem is interesting I don't think it applies, since with a time limited copyright we would just assume that at the end of the copyrighted time the journal/love letter would enter the public domain... 
 
We can just assume there are private and public documents. 
 
Copyright came about during a time of low technology, when it was actually hard to copy something, now that it is easy we no longer need it.
