Dear Vincent: well said. Austrian economists are not big fans of "perfect competition." I'm glad you recognize that high concentration and monopoly are very different things. This might be of interest:

A question that is worth elaborating on: if the market price of a unit is greater than the cost of adding a marginal unit (e.g. $3 for a unit of beans), why wouldn't a competitor move in to offer more beans at a lower price that is closer to $3/unit?

The invocation of "barriers to entry" or "economies of scale" as an explanation for such a situation merely begs the question about the optimality of the market price. What is the cost of overcoming the barrier, or of doing business on a smaller scale (dealing with fixed overhead costs, etc.)? If the market price premium over over the marginal unit cost is insufficient to cover the unit's quotal share of additional overhead expenses, of additional expenses associated with transcending a barrier to production, etc., then isn't it more efficient to have a higher level of market concentration to avoid excessive non-marginal expenses?

It doesn't make sense for economists to assume "perfect competition" when one's capacity to compete in a particular cost has a cost associated with it. The only basis for criticizing a market price premium over marginal cost is if the "barrier to entry" cost or overhead cost does not reflect natural constraints on production, but instead reflects artificial coercive restraints on production. A government or a non-governmental gangster that continually threatens force to prevent competition or to make competition more costly is not economizing on factors of production as does a non-coercive "monopolist" where the lack of competition serves to minimize wasteful duplication of entry and overhead costs.
