Sources of market power

Market power arises from two sources: violence which avoids competition from other market participant and the favor of the people with which the market powerful trades. There is no third source whatsoever.

False dichotomy between profit and utility

The whole difference between the economic analysis of a consumer and that of a producer for the market is this: when you analyze a consumer you only pay attention on how the consumer tries to optimize value for himself while when you analyze a producer for the market you pay attention on how the producer tries to optimize value for buyers as a means to optimize value for himself.
