Markets used to be hundreds or thousands of people who were roughly peers and they still work well in that situation. When I go to the riverside market on Saturday to buy fabric for a project, there are 10 different fabric stalls. On this one little river bank alone! Each one of them has a different selection and they all want me to buy their fabric. This is the only thing that people used to think of as a market, and it probably does work well. Since that time, however, the term has been twisted beyond comprehension.
