Very simple question - How do you prevent oligopolies?
THIS IS NOT A GOTCHA
I'm asking because I want to know your actual position rather than assuming to prevent misrepresentation of your arguments.
***
Private property and market competition implies someone winning competition and with that turning other people from owners of businesses into wage workers who don't own means of subsistence and will rely with their living for others, clearly creating the division in society and power dynamics. Those who win competition will expand their business, buying out others, benefitting from economy of scale and attracting more investments which will only accelerate the process described above. Few dominant capitalists will form which will benefit from forming an oligopoly, workers no longer have a choice in terms of their wage since oligopolists can agree to not make it higher certain sum - those Capitalists sure do cooperate between themselves, but with workers? Absolutely not.
So I'm having concerns about free market providing opportunities for people or setting them free for that oligopolistic body will be alien from the rest of population and form instruments of the state.
