I would auction shelf space at my mega chain grocery store to large brands. The highest bidder would have the opportunity to buy up all the shelf space in order to bury any potential competition. The bidder could create 100s of different labels of essentially the same goddamn product, in order to maintain the illusion of choice, maximize consumer confusion, and thus maximize the time a customer spends thinking about the shelf-dominant brand, for some otherwise dead-simple purchase, such as toothpaste.
