Why can't people have all the goods they want In economics?

People cannot have all the goods they want due to the fundamental concept of scarcity, which arises because resources are limited while human wants are virtually unlimited. This limitation forces individuals, businesses, and governments to make choices about how to allocate resources efficiently. Consequently, trade-offs occur, meaning that acquiring one good often requires sacrificing another. In essence, the scarcity of resources leads to the need for prioritization and decision-making in economic activities.
