Please simplify this for me. Cant understand this at all.

Laissez-faire is synonymous with what was referred to as strict capitalist free market economy during the early and mid-19th century as an ideal to achieve. It is generally understood that the necessary components for the functioning of an idealized free market include the complete absence of government regulation, subsidies, artificial price pressures and government-granted monopolies (usually classified as coercive monopoly by free market advocates) and no taxes or tariffs other than what is necessary for the government to provide protection from coercion and theft and maintaining peace, and property rights.

Laissez-faire generally means that something is done (or allowed to happen) without much, if any, interference. You can also apply the term to how people do or don't choose to raise their children!

Where did you get this passage? The second and last sentence has 65 words! No wonder you can't understand it. It's hard for me to break down into a usable message.

Laissez-faire refers to an economic system, popular in the 19th century, that emphasizes a free market without government intervention. In this system, there is no government regulation, subsidies, artificial price controls, or monopolies. The only role of the government is to provide protection and maintain peace, along with ensuring property rights. Overall, laissez-faire is the idea of a complete absence of government interference in the economy, allowing the market to function freely.
