What luxury goods sell (art, handmade Rolls,...) is a story, not a product. The category that looks more likely to suffer are the luxury goods that are merely almost-luxury products - industrially manufactured but high priced (I'm thinking Nespresso here). What will hurt them is the increased transparency - the cold spotlight on their industrial value chain. They will be exposed as fakes.
But what will likely thrive is everything that has nothing to hide but everything to gain from this new transparency - everything that is ugly, earthy, hand made, at the expense of sweat and blood and occasionally the lunacy of the artist or artisan. That stuff will probably become astronomically expensive.
And then, someone will figure out how to produce that semi-industrially and we can start over again ;)
