Costless Goods
Costless goods are items that are available without any monetary cost to the consumer. These goods are often abundant in nature and can be accessed freely, such as air, sunlight, and water in certain locations. Because they do not require payment, they are considered to have a zero price in economic terms.
However, while costless goods may not have a direct monetary cost, they can still be subject to scarcity. For example, clean water may be free in some areas, but overuse or pollution can diminish its availability. Thus, the concept of costless goods highlights the balance between abundance and sustainability.
