I don't think one can sell the internet on the internet because simply that the consumption of the internet will then have to depend on the internet which is not possible in terms of the industrial string theory I have developed some with my young son Sandipan and Mr. Nick Hamburger which you can find on my RG page. There is a sequencing of the econophysical actions which follow the Arrow of Time postulate and are DBranes Strings differentiable. I hope I have answered it correctly.

Your question is not clear enough and can be interpreted in as many ways as the backgrounds of the reader. That said, in the past, luxury goods were not sold on the Internet simply because that would detract from their image of being luxury goods. Luxury goods were and are supposed to be bought, owned and used by the elite, the rich, the powerful. You can try to find out if certain products with exclusive brand names can today be bought on the Internet... just think of an exclusive product.
Another obvious example could be military equipment like tanks, howitzers, jet fighters, submarines, etc. I suspect that there might be the possibility of acquiring these through other, under the radar suppliers.
In the U.S., some businesses that are considered to be of luxury brand tends to not sell their merchandise online. An example would be Prada. Im not sure if Prada is a U.S. company, but they tend to not sell their merchandise online. The primary argument for this is that selling online erodes the value of the brand. Another common argument is that selling online prevents consumers from having the "in store" luxury feeling. There are plenty of articles that you will come across as you search online for this topic. Nevertheless, I am referring to the apparel industry.
