The people in Venezuela "need" toilet paper.
The "need" for a product does not cause it to come into existence.
The only products that can be "consumed" are products that have been produced.
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.
