I'm not sure how you get there. All I said was that if the characters have deep stories, it can be hard for the Gm to find resolutions to those stories when the PC disappears. Ostensibly there are NPCs, factions and whole chunks of the world under the auspices of the GM that must be dealt with.
Or, I guess you could just completely break any sense of verisimilitude and ignore it all.
All I was saying was that a clean slate, where a new party picks up the main quest of the campaign (if such a think even exists) is easier ON THE GM than dealing with the death of a singular PC in a heavily PC focused campaign. Is this controversial?
