The more demand for money there is, the less risky it is for an individual person to hold money.

Similarly, the less demand there is, the more risky it is for a person to hold it.

If you were the first person to sell goods or labor for money, then you would probably look insane or immensely stupid to bet that other people would want this stuff in the future.

On the other hand, if many people are using money, then you are merely depending on there not being a hyperinflationary event in the immediate future.

In that case, you might look insane or stupid for worrying about such a remote possibility at all.
