Contrary to popular belief, competition doesn't work because people think up brilliant ideas for products and sell them.
It works because people think up all sorts of ideas for products. Most of them are stupid and die in obscurity. A few are good and go on to success. Many of the ones which die seem brilliant, and some which succeed seem stupid (e.g. Pokemon cards). The market is the final arbiter, not your nor my opinion. If we blocked product ideas on the basis of people calling them stupid, technology would never progress. Most people thought the Wright brothers were going to get themselves killed trying to build a flying machine.
