Should the kurds have a nation-state like every other nation?

The answer is 'YES'. I think it would be in every ones best interest if there were a simi-autonomous Kurdistan within a Greater Turkish Republic. It's too much to hope for but I think that it would be the most 'stable' arrangement. A totally 'free' Kurdistan, existing in what was Northern Iraq would be seen by Turkey as a threat and by Iran as territory that could be annexed 'for its own good' to protect it form Turkey.
