How to protect is benificial to public goods to private goods

a Private GoodA private good is a product that must be purchased to be consumed, and consumption by one individual prevents ANOTHER individual from consuming it. In other words, a good is considered to be a private good if there is competition between individuals to obtain the good and if consuming the good prevents someone else from consuming it.Economists refer to private goods as rivalrous and excludable.BREAKING DOWN Private GoodExamples of private goods include airplane rides and cellphones. Private goods are less likely to experience the FREE rider problem because a private good has to be purchased; it is not readily available for free. A company's goal in producing a private good is to make a profit. Without the incentive created by revenue, a company is UNLIKELY to want to produce the good.A private good is any item that can only be used, or consumed, by one party at a time. Many tangible home goods qualify, as they can only be used by those who have access to them. Any item that is effectively destroyed or rendered unusable for its original purpose through use, such as food and toilet paper, are also private goods.Often, private goods have finite availability, making it excludable in nature. For EXAMPLE, only a certain number of a certain pair of designer shoes is produced, so not EVERYONE can have those shoes. Not only is a single pair seen as a private good, but the entire product line can be included.The majority of private goods must be purchased for a cost. This cost offsets the fact that the use of the good by one prevents the use of the good by another. Purchasing the item secures the right to consume it.
