That falls under point 5 - no real evidence, just thought experiments. I don't really agree with that argument - 'real evidence' is always elusive - at some point we always have to do thought experiments - but I think you need to go a bit deeper. Your examples assume the business model of current copy right related businesses - it is obvious that in a world without copy rights they would not function, but that does not mean that we would not get the things that those businesses produce - they could be produced in other business models.
