State creates monopolies by stopping free actors to enter the market by:
- IP rights
- Protectionism, tariffs, Quotas etc.
- Exclusive rights and laws generated by Lobbying
- Unnecessary Licenses and regulations (often with public health excuses)
- Uneven Taxation
- State ownership of production
Surely all capitalists desire to be a monopoly, but free markets is the only power to stop them.
On the actual subject, the game "Monopoly" implies Capitalism, but to me it is just a game.
