The problem is that the companies producing luxury goods benefit from providing as little information as possible to their customers. It would be better for society if the companies with the most knowledge of how to produce a particular type of good could be incentivised to educate consumers rather than to capture as much consumer surplus as possible with dubious market segmentation partly based on keeping people ignorant.

This seems to me why people complain about IP laws. They encourage one type of good behaviour - innovation - but also discourage another type of good behaviour - sharing.
