Whiich is fantastic. I mean, if the DM wants to do all the work and actually does it, I'm pretty sure no player is going to complain too much. Great. Wonderful for you.Personally, I'd be pretty hard against it. As a GM, worldbuilding is one of the tasks that I enjoy most. Suggesting that the players have just as much responsibility for it is like suggesting that someone else has just as much responsibility to eat my dessert as I do. No, stay away from my raspberry cheesecake!
However, I don't think writing the game for someone who has the time and energy to actually do all that work is a good idea. I think it is better to teach groups to share in the work so that we build more DM's. To me, that should always be the primary goal of the DMG.
