Obviously, any Gm can (and it semes many will) create house rules to make "non-magical materials" listed on the new designer-dr charts rare in order to make designer-dr work.
In a world where silver weapons are sometimes needed and where cold iron weapons are sometimes needed its not inherently logical to design the world so oblivious that they are not prepared.
Even once we get past the notion that these weapons are for some reasoning RARER than magic enchanted weapons, the logic falls down.
To my mind the logical solution to the problem "dr values are trumped by magic weapons and GMW" is to change the values so that the trumping is not so absolute... not to turn mundane materials into some rare weapon category. Magic should beat mundane.
Making werewolf non-silver immunity not beatable by magic weapons, but leaving it still helpless against magic missile, ray of frost, and lightning bolt doesn't salvage the werewolf's "traditional feel"... it just makes carrying around a silver dagger sensible.
That Gms can and likely will make silver weapons and cold iron weapons and designer-dr-material-weapons-de-jour-from-the-latest-dragon-beastie-corn-cob-clubs rarer and harder to find that plain ole magic weapons is not even in dispute.
What is in dispute is is this "solution" a good one or one thats a cure worse than the original affliction.
its obvious where I sit, others will come down differently.

Nobody said they were going to make ALL materials rare...
IMC there will be a difference between ordinary steel and "cold iron". Maybe everyone with 1 skill in Craft (weaponsmithing) can handle "Cold Iron". Whatever rocks your boat man... Even so, consider the likelihood of such a weapon being a practical weapon, do you truly consider that they will be readily available for purchase? Or would it be more likely that it be constructed to combat a specific threat?
Silver, same thing. Not many weapons are going to be manufactured in Silver, UNLESS there is a bloody good reason. Maybe in a place where lycanthropes are running rampant. Otherwise, silver swords aren't going to be found in your everyday weapons-mart. YMMV.
