There are different ideas of competition in economics. Mainstream economics defines a static competition with an infinite number of sellers and buyers, perfect knowledge, while Austrian economics defines a dynamic competition that promotes entrepreneurial activity, innovation, and differentiation. Most real world competitive practices are condemned as monopolistic by static competition. The real definition of competition is freedom of entry. Governments can block competition by protecting local industries, or by creating patents and licenses. The consumer is protected by freedom of entry, innovation, and entrepreneurship and not by monopoly policies, regulations, or licenses.
