TFT maximizes utility. If it's one round, then Defecting is the best strategy (well, it's the paradoxical best). Also, the last round of a single game, defecting is best (unless multiple games are going to be played).

But if you agree with this, then surely you can see that if both players know this, they will also defect in the next to last round?

Not if 1) they don't know how many rounds are in the game (which is why I disagreed with your #5 assumption earlier), or 2) they will be playing multiple games (thus, making it as if there was no known ending to the game).
