Ah, thanks. Now I see what you misunderstood. The point of making the argument high level is because then you're able to 1) see the depths of your ignorance and 2) see where you need to move to remove that ignorance. Moreover, the best arguments are going to be written out more completely somewhere else anyway (probably books).

For example, if you're arguing at a high level that porn should be illegal, you could import the work of other people to support you of which the details have been argued -- and this makes sense if your argument is representational of the highest level of thought within that area.
