Actually it does. People who transact are realizing the benefit of money - the avoidance of barter costs. Those who never transact, never realize any benefit.

Chain security - censorship resistance (as opposed to individual double-spend security), is entirely dependent upon tx fees.

There is zero point in saving if you never spend. You can instead just burn your coin.

A hoard decays naturally due to opportunity cost. Investing it requires transaction to invest, and transaction to earn (profit), and transaction to return it (interest).

Demand is the only reason we save, and eventually transacting is the only motivation for saving. No transacting implies no demand - and no security.
