A very valid argument on the contrary. It's an valid theory, as valid as any other.
@garile, you play your role in the settings but you don't play in the game virtual reality.
the char exist in the world, the world in the settings. You can't be IC without being in the world.
You are right to ignore cars and microwaves, because they are not part of the settings therefore not part of the world. (you can /report and /ignore those)
But you can not compare swords, to microwaves. swords are in the settings and in the world.
