Perfect only exists in models. Also, you might think of it as thousands of sellers but only two buyers. In any case, competitiveness has to do with more than the number of actors. Switching costs are pretty low and information is very available. That counts for a good amount.

Generally though I agree that the market needs more players, for the employee vs sole trader debate and for competitiveness reasons.
