As they say: "the edge bone's connected to the...bevel bone". Or something like that.

Scratches on the bevel reach to the edge. Sure, they don't tell you how far apart the two sides of the bevel are (ie how "wide" the edge is) but I think in this discussion we are assuming the edge is "sharp" aren't we?

So while I don't disagree that we shave with the edge, I do disagree that the bevel has nothing to do with it. It's like saying a car drives with the wheels.
