Antitrust and the government intervention

Many appear to strongly resist any government intervention because it is against free market and they believe that free market alone will solve various social problems. Putting the debate about whether free market will ultimately solve various social problems or not aside, we need to recognize that so many things in our society have been heavily subsidized already. Governments all over the world created roads. US government initially funded the development of the internet. Neither TV nor radio would have been adapted without the government subsidy. That is not to say that the government intervention is a must and that the government should always intervene. However, it seems that many forget that the government intervention is a pre-condition, i.e., something that took place already. Discussion about antitrust often captures this; "Company ABC123 does not have to comply with the government's request because it is anti-free market. They do not have to behave in a certain way for the government to break up the trust. Etc., etc., etc." Many appear to have forgotten that these companies in question were able to get to where they are today because of the government intervention such as the enforcement of antitrust laws. It is rather silly to argue that it was ok for these companies in question to receive the great benefit of antitrust laws, yet it is not ok for the government to enforce the same laws on them today.
