Why is some degree of Monopoly power permitted?

A monopoly firm is one that operates in a sector with little or zero rivalries, and it can determine its conditions and rates when dealing with customers, rendering them extremely competitive. The monopoly has the benefit of economies of scale and the advantages are transferred to the customers. In a society, a certain level of monopoly control is required, because people may abuse their privileges. Electricity production and processing were limited to the monopoly sectors. The explanation for this is that if everyone can transfer electric power then unfairness might disrupt the economic system. To discourage corporations from exploiting consumers, the government must regulate other facets of the economy.
