Not really. Dozens (apparently) of appropriately-leveled characters barely defeated the first floor boss. It would plainly have been impossible for one person, no matter how personally skilled, to do anything - in fact the main combat mechanic displayed in the first three episodes.is a mechanic that requires a party. One person blocks or deflects the boss's attack and then someone else switches in to actually get a hit in on the boss. Naturally Kirito is a master of the usage and timing of this mechanic despite not partying with anyone. Combat is also extremely simple for a multitude of reasons, so once again, individual skill is not a huge contributor to group success.
The obvious choice would be for absolutely everyone to refuse to play the game and wait until the creator is arrested and they're removed from the world, but that would make for a pretty boring show.And do you seriously want to fight enemies of the same level in a game where dying means death in reality? It makes sense to maintain a certain level advantage over the content to ensure survival, but not too much that it would be too inefficient.
I'm not trying to argue that I need more MMORPG tactical realism in the show, mind you. It's just that his character doesn't work at all within the context of the world. He's a loner, but he's the wrong kind of loner to be good at what he's doing, and the show doesn't care enough to make sense of that. He is just the best because he's the main character/
