Wow. Superb answer, just what I was looking for. I'd actually heard your point 2 repeated several times, so I guess it's a common idea.
By the way, one of the reasons I "like" Go (in a purely objective, looking from a distance without learning it kinda way) is that, from what I've heard, even average players can beat computers at the game. Obviously, this is mostly to do with accidental, mechanical facts about number of possible moves, but in an age where Chess has been "won" by computers, it is something of an appeal for me. Do actual Go players feel the same way?
