I doubt that LVMH products are as hard to replicate as technology. People who pay for luxury goods do not care for the product itself but for the prestige it carries. The products LVMH sells are proof of social standing, which are the final token in a chain of trust that would also include LVMH retail stores in which one can be publically verified to be actually shopping and buying - the elite wouldn't be caught dead in a mall selling counterfeit products.
