"Options" not withstanding, magic weapons are not only essential, they are indispensable. But no one is suggesting we drop ACs... because one has the option of having various enchantments on a weapon rather than straight bonuses? That's not even in the same sport as this discussion, let alone the same ballpark.
If you want to compare weapons to CoRs, you have to go with the straight numeric advantages. Everyone needs enchantment modifiers on weapons eventually (to hit and keep up in damage output); eventually everyone needs resistance modifiers to saves (to pass the DCs).
So, enchantment modifiers on weapons are inevitable, too, but again: you're not complaining about that... supposedly because "magic weapons" appear in fantasy mediums. Just because there aren't different options for a resistance bonus doesn't make their function any more mundane that the function of an enchantment modifier to a weapon; the net results are pretty much identical: higher rolls. Except the latter is okay in your book and the former not, and this judgment is based primarily on the illusion that one is forced upon the PC more than the other, when the truth is that both are roughly equal in necessity.
I'll just go ahead and say that we'll have to agree to disagree on the subject. I think a 1-or-20 situation is more likely the higher you go, but I wouldn't use a rule that ensured it.
