I have nothing against multiclassing per se, it's just the idea of simply taking a level of cleric, rogue or ranger simply to min/max your character's killing capacity.
If it's part of a character's organic development and evolution, and there are in-game reasons for doing it, then by all means.
'S'cool. I've just run into quite a few rather vocal individuals who assume the first to be directly contravening the second. It's possible to multiclass to follow your organic development and evolution
and improve your "killing capacity" at the same time. (In fact, one would hope that most multiclassing does this, because single-classing usually has that effect and most people don't seem to mind that!

See, this is what upset me so much in the first place and led me to post my "Does 3E dictate a certain style of play?" thread several months back. Many people, such as MerricB, told me that it didn't, but Doug apparently disagrees.
Rather, I think Doug is pointing out some of the drawbacks of your proposed lower-magic system.
The rules of D&D as they stand assume you'll be giving out a certain amount of treasure, and that most of that treasure will be converted into "player upgrades."
Accordingly, a monster who has a specific type of Damage Reduction is an appropriate encounter for a certain level party because, at that point, the fighter will have the magic sword he needs to fight it effectively.
If you take away that magic sword (or, perhaps worse, make it only available to the cleric!), then the monster is more challenging. It's book-listed CR is no longer true.
Similarly, large, brute combat monsters tend to have relatively low CRs because, once the party reaches a high-enough level, they're assumed to have mobility-increasing magic and spells (like various methods of flying). The big dinosaur isn't as dangerous to the group, then, because at least several characters can stay out of his reach. If you take those abilities away, the T-Rex is much more dangrous.
So, I'd read Doug as more of a cautionary note (Don't believe what the books tell you is likely to happen when you've changed some of the core assumptions!) rather than a claim that D&D requires certain things.
It cheapens magic, I think, to believe that an enchanted sword or shield could be disposable as soon as a better one comes along. I highly doubt Thorin or Gandalf would have discarded Glamdring or Orcrist, for example.
Yeah, if I had an artifact sword, too, I'd be hard pressed to throw it away.
Of course, +1 swords aren't really artifact level, either.
