The assertion is false. Not all consumption goods are durable. Consumption goods are categorized into two types:
Durable Consumption Goods: These endure for an extended period and can be utilized multiple times (e.g., cars, televisions).
Non-Durable Consumption Goods: These are fully consumed in a single use (e.g., milk, food, fuel).
Therefore, consumption goods can be either durable or non-durable.
