With a fixed supply of money, holding the money itself is similar to investing in a global index fund which offers no yield but appreciates with global productivity. Anyone can be an investor; zero fees, experience, or professional management required.

Anyone who earns money can expect to keep it and watch it appreciate, without needing to do any more work.

With easy money, you need to beat inflation to keep the value you earned & for that, you need several professionals working full-time trained for years and plenty of luck

Imagine if every child could expect any money they earn or get as a gift to appreciate over time without needing professional management. How much more would children grow up to value saving and low time preference?

Imagine if every professional could focus on their job and watch their savings accumulate & gain value without needing to have a side job trying to figure out what stocks, bonds, commodities, and other arcane instruments to buy & who to hire to manage them all?

Imagine if the old, retired, and widowed could just count on their savings maintaining value without having to follow & speculate on global macro trends & insane monetary policies.
