I love how one can make an example (gold coin) to illustrate an issue (debasement) to receive a long lesson about the example being incorrect instead of discussing the issue. I never said "gold is the solution", and in fact my example is about how governments historically debased gold coins.

An egyptian government can also "debase" grain. Just issue fake receipts for unexistent grain, and buy things with them at current prices. Suddenly, there are a lot of grain receipts circulating, so you expect prices to rise. The government can now blame the price rise to the merchants! They are the ones that are rising the prices, and that's all you can see.

On the example of the grain deflation, you don't have a "receipt in gold". You buy or sell grain, and that's it. Lets suppose a simple market that stores grain at a cost of 10% in a year. You sell grain on January for 100 ounces of gold, but if you try to re-buy the same amount of grain in December, it costs 110 ounces, or receive a 10% less grain for 100 ounces. As simple as that. Your 100 ounces of January didn't guarantee you the same amount of grain in December, because they are not a "receipt in gold for X amount of grain". Prices are a dynamic way of economic coordination to reflect whatever reality it may come. E.g. if half the silos burn through the year, grain prices will double to reflect that, and that's not inflation. But good luck reclaiming your clay receipt amount of grain.

The problem here is not the gold. The problem is issuing more money than people are demanding. There is nothing wrong with issuing money (e.g. in form of new credit) if people demands credit that they are paying sooner or later. The problem is the government creating new money with zero intention of paying it back, because that fuels inflation.

Deflation is not bad _per se_. We have deflation in computer or mobiles prices since forever: we know we can buy a cheaper computer in the future with the same specs than today, yet we don't hoard money instead of buying computers. We buy them when we really need them. Inflation creates an artificial urge to spend sooner than you want/need, because we know our today money won't buy the same in the future but less. That looks like a good thing on the surface ("the economy moves" they say), but it has a lot of bad consequences: erodes savings, consumption rises above our real needs, investment is more difficult because economic calculations are uncertain.

Historic inflations are well explained here: https://www.amazon.com/Forty-Centuries-Wage-Price-Controls/d..., where the authors collect a large number of inflation events in the last 4,000 years and show how every single government followed the same route: 1) debase the money, 2) expend their newly created money, 3) prices raise, 4) people complain, 5) government blames the merchants and creates laws to control prices and punish price raises 6) inflation persists.

Wage & price controls have been tried for 4,000 years. They have never worked yet. But this never discourages people from trying them again.
