That doesn't make sense. Pirating something means you gained the whole value of the product. In Tiffany's case that's not remotely the case. In fact, they will pay large sums of money to marketing companies to make sure you get a photo.
If the entire value of a product can be taken, there's no incentive for it to be created in the first place other than intellectual curiosity - as another commentator said: effectively academia.
Our society has never found a way to deal with digital products in a way that doesn't skew incentives
