Magic items are optional, you aren't supposed to use them unless you are willing to put in the extra work for a rebalanced game.
People keep saying this, but it just isn't the reality of the game. I'm going to go out on a limb and say that the vast majority of D&D games use magic items. I would think that D&D campaigns that don't use any magic items at all would be in the very tiny minority. I think that when the designers said that the game was built without magic items as an assumed part of the math, they meant that, unlike 3.x and 4e, characters don't need a certain number of magic items at their level just to keep up with the game's math, not that they expected a no-magic-item game to be the default assumption.
