Wow, you have no idea how deep the ramifications of that would be, do you? Let's say you need a toothbrush. Where do you buy it? At the store. Okay, but there's a problem. How did the company that owns the store choose which toothbrushes to carry on its store shelves? Was inter-corporate advertising involved? Is that illegal under your scheme? Or maybe the manufacturer paid the store for shelf space. Is paying for physical product space meaningfully different from paying for billboard space? If the shelf space is legal in your utopia, then can the billboard be legal, as long as it only features a bland iPhone 4 photo of the product, along with the product name in a monospaced font (wouldn't want to AdVerTiZe!). Or is all of this disgusting to you, and you want a government agency that tracks finds product vendors and produces a huge book of products that you can peruse, but, all of them are listed without any embellishment, so you have to compare toothbrushes on raw metrics like length, with, plastic composition, angle of attack, bristle circumference, mouth feel, water retention, etc. and then you order it directly from the government.
