Well, oligarchy is the eventual result of liberalism. Even though we may have started equal, some people, through luck or questionable methods, have attained a position of power, possibly by being owners of a company that has a monopolistic status. And now, via regulatory capture and targeted actions against competitors, looks to subvert the "free" hand of the market.

Why can't you get decent internet in the States? Because on each location there are two or maybe three companies that collude to keep prices high. And when you try to start your own ISP, suddenly these companies offer crazy good/under cost prices so that your new ISP is unable to survive, and then jack up the prices again.

Of course, at any point, as a consumer, you are absolutely free to enter into a contract with whatever ISP you want. If only there were a few more...

Now tell me how do you fix that without bigger state imposing specific regulations.
