Please read this and give me suggestions on what I should add to it. (End goal is 400 words) "A monopoly is any business that has dominated one sector or industry; monopolies can also be described as a seller that faces no competition. They are the sole seller of goods with no close substitute.

There are two types of monopolies; the first being "natrual monopolies" and the second being "competitive monopolies." "Natrual monopolies" are government-supported monopolies made by the company being the only provider in the area. In comparison, "competitive monoploies" are made by customers choosing to use a specific business due to things like better quality, lower prices, and ease of use or product availability.
One example of a monopoly would be how certain service providers will force people to use their services due to them being the only option, but then cause them to either pay way more than necessary or make it hard for them to do anything because of the anti-cooperation from the company."
