By the same logic, energy products just provide a kind of psychological comfort. As long as they don't create a dependency or cause harm, as long as they are not used to dupe people or are not priced sky-high, there's no reason it shouldn't be "to each according to his needs."
同理，就算能量商品只是一種心理慰藉，只要不造成依賴與傷害，不要有欺騙或哄抬價格，也不妨讓大家各取所需吧？
