Not really, because in the information age, monopolies require government intervention to become and maintain a monopoly. Regional monopolies such as utility companies are created because government literally forbids competition. When we look at the FDA which would not exist in a capitalist country, it has so much regulation and red tape that it takes drugs a billion dollar and several years to come to market. It is just impossible to have no competition unless you either buy politicians to make it possible such as the ones bought to create the FDA, and the ones bought to create regional utility monopolies.
You see capitalism is against economic interventions in favor of any or even all businesses. Did you know that the courts determined that corporations are people? This was done so companies could buy or intimidate politicians through lobbying. They literally lobby government to create policies beneficial to them. In a capitalist society, the laws would be unalterable in that regard and no amount of bribery or threats could penetrate the law and make that happen.
