Actually Kibou has a terrifying point.
In the first couple months of SAO, over 2,000 people died, and zero of that was from PK behavior. Moreover, if every Beta tester made a guild to guide new players, they would only need to manage nine people each. Looking at the scenario from a purely objective long term standpoint, it was within everyone's capabilities to save many of the people that died in SAO.
Kibou, though was not as you point out, thinking objectively. He's one of those players that cares about little else than himself and what he can swindle from others. That doesn't make his point any less relevant. Many of the Beta players literally abandonded players in a game who could no longer trust in the game's systems for a short term goal. And it showed no benefit, it took several months to clear each floor.
