And without consumption, there is no production. If there isn’t a demand for something, then there will be no production (and no product being produced).
For example, toilet paper might not be needed if it weren’t for the toilet. No one needs toilet paper and it is only a recent invention. We did fine without it since the beginning of time. It was because a need was created or maybe realized that it is produced.
How do you consume something that has not been produced?
Demand does not create supply.
