Agreed completely. Maybe playing with no dice rolling, no sheets can be ok for a casual 2 hour game, if you and your players just want to rp a bit. But for a longer game, the DM's whims are too much of an issue, because even the best DM with the best intentions will have a bad day sooner or later, and that could be easily reflected in his subconscious deciding "The trap cuts your head, stupid halfling... you're dead." rather than "The trap springs hurting you badly, poor halfling. You need healing."
But you can't count on that! You have to assume that everyone at the table is there to have fun, and it would be in everyone's best interest to play fairly, reasonable and trust each other. You can say the same about players, a player can be having a bad day and take it out on the group and DM by running amok and ruining the adventure, and therefore the night for everyone. The best game in the world, whether it's no-rules, rules-lite or some mega-simulation, can be ruined by any gamer having a bad day.
Anyway, the point of jmucchiello's post has nothing to do with whether rules-lite/less would work for everyone, it should go without saying. He's just saying that a good DM (which is the assumption) can adjudicate anything as needed, when needed. And the DCC rules definitely makes this assumption.
