Jackson monopolized the scarce resources of his own dance and voice. He is the only one, so it can be judged that this market belongs to a complete monopoly market.

Hehe, this question is very interesting. In fact, the fundamental purpose of anti-monopoly is to prevent the interests of most people from being harmed by the emergence of monopoly. However, Jackson's question should be understood this way. Jackson is so famous because of his unrepeatable nature. If there were a lot of Jackson, the fans wouldn't faint with excitement. Monopoly is to seize the interests that should not be monopolized, and Jackson himself cannot apply such rules.
