Antitrust law absolutely does not require consumer harm. Consumer harm came about after Robert Bork wrote his book and convinced SCOTUS that his interpretation of antitrust was correct. In fact, before Robert Bork, Courts tended to view competition as more important consumer harm. Lack of consumer harm requirement is starting a comeback because it's during monopolization effort, consumers actually benefit from low prices. Once monopoly cements itself, prices tend to skyrocket and quality go down because factors make it very difficult for competitors to emerge.
