I would like to think that as the quality of the work improves, it makes more and more sense to establish your own brand instead of duplicating the work of another entity. Of course it all breaks down if the faked brands aren’t making all that high a quality items.

Presumably the perfect fake often costs too much to reliably manufacture.

Think of the randomness inherent in the microscopically unique features of the original and how you might emulate them reliably with a margin that still lets you compete with its luxury pricing.

Diminishing returns on perfection.
