That diagram assumes an adversarial model of discussions. Note the use of words like “concede” and “forfeit”. I prefer to get into discussions where the interests of participants are aligned, e.g. everyone wishes to find the truth. This way you never need your opponent to “concede” anything, in fact you’ll try to fix your opponent’s arguments for them.
Such “rules” may help in discussions with misaligned incentives, e.g. when you’re trying to defend your theory or convince spectators that you’re the better debater, but avoiding such discussions seems to be a better strategy.
