What money actually is

Imagine this

It is 1000 BCE. You grow wheat but need shoes. The cobbler does not want wheat — he wants oil. So you need to find someone who has oil, who wants wheat, and who is willing to trade with the cobbler. Economists call this the double coincidence of wants problem, and it made trade a complete nightmare. Money was invented to fix this.

Money works because it solves three problems at once. It is a medium of exchange (everyone accepts it), a store of value (you can save it for later), and a unit of account (everything gets priced in it). Without all three, it breaks down.

The rupee in your pocket has no inherent value. It is cotton paper. What makes it worth ₹500 is that the Government of India has declared it legal tender — fiat currency — and hundreds of millions of people agree to treat it as valuable. The moment that agreement breaks, the money becomes worthless paper.

8 November 2016 — PM Modi declared ₹500 and ₹1000 notes invalid overnight. 86% of India's cash became worthless in hours. The notes did not change. The government simply revoked its declaration. That is how fragile the whole system is when trust breaks.

What makes a ₹500 note worth ₹500?
