That's a pretty broad generalization.
It would all depend on the denier of the silk.
What are you comparing really? Kevlar as thick as a sweater and silk as thin as stockings?
Or the other way around?

If we are talking pure stopping power we don't know how thick a weave or how many layers we need to even compete with kevlar at an even pace.

The only real comparison we have is mundane silk.
You have mundane silk at $21 a yard for whatever that yard happens to be.
I do not see a matching yard of DS going for less than $50
A matching MS yard would probably be around $30 IMO to be competitive in the same market with the benifit of spidersilk as the premium.
