Scarcity in economics arises because

Scarcity in economics arises because resources are limited in supply relative to the demand for them. This means that there are not enough resources available to satisfy all of the wants and needs of individuals and society as a whole. Human beings have unlimited wants and needs, but resources, such as land, labor, and capital, are finite. This creates a situation where people must make choices about how to allocate scarce resources among competing uses. In other words, scarcity necessitates that individuals and societies make trade-offs, as they cannot have everything they want due to the limited availability of resources. Scarcity is a fundamental concept in economics, as it drives the study of how individuals, businesses, and governments make decisions about how to allocate scarce resources in order to maximize their utility or well-being.
