In most cases, markets are considered more efficent and better off when monopolies are broken up. Why is it hard for governments to do this

In simple words, it is hard for governments to break he monopolies as generally as these entities are generally protected by some kind of legal or social convention. A monopoly of an entity that has strategic importance for the nation could be harmful in long run. Also if an individual owns a monopoly due to some patent right etc. then breaking that up will be seen as social injustice.
