In a free market, competition has end results. Buisnes don’t just keep competing with one another ad infinitum. One of them eventually cant keep up and closes shop. It’s competitors expand into the space it previously filled. This process repeats until you have fewer and fewer firms that account for more and more of their sector of the economy. New business do not have resources to eke out space in an already filled niche.

Under a long enough time frame, a free market creates less competition.
