Final answer:
Excludable goods are those that not everyone has access to, and money, power, pleasure, and pain are considered as such. They are all finite, tradable in some form, and come with the need to make choices due to scarcity.
Step-by-step explanation:
Money, power, pleasure, and pain are all excludable goods. These elements are considered excludable because not everyone can access them freely; access is often restricted to those who can pay or have certain privileges to use them. Money is a medium that people use to trade goods and services, and it has different forms in various cultures. Power often comes with money, influencing decisions that can affect the job status of millions. Pleasure can be described as a state of mind with various forms and is subjective to the individual's experiences. On the other hand, pain is something that individuals seek to avoid, yet it is an inseparable aspect of human experience.
Pleasure as a concept is multifaceted, including sensory, affective, and mental experiences. It can range from the joy of achieving a goal to the satisfaction of learning something new. Private goods like a slice of pizza are rivalrous, where only one individual can enjoy it at a given time, emphasizing the exclusivity of such goods.
