This is the core problem of economics. If we solve it, we solve, well, the economy. Nobody would need to buy anything; we could just produce and send everyone what we know they want. No need to consider unpredictable variations in individual choice and discretion.

Of course when you include that pesky individualism, this model breaks down. Because it becomes impossible to structure production today to perfectly meet demand tomorrow. Making currency transformations across eons breaks down because it doesn’t make sense to ask how many talents of silver Caesar would have paid for an iPhone.

No? Are you confusing what you described—which is the aim of price-level targeting—with fixed-price policy?

There are people who seem to literally believe that without inflation people will refuse to invest in anything and choose to return to a cave-dwelling existence. I don't know how prevalent they are, but they turn up in these sort of threads.

No. The problem comes without increase of the money supply. If there isn't enough growth to support the growth of the economy, then yes you're definitely hurting it (and if the supply is fixed, then your economy is going to be practically deadlocked).

The nice thing with commodity currency in the preindustrial era is that they accumulate roughly like the overall capital accumulation and productivity so it kind of works (it's not optimal though, and the massive increase of supply from the “new world” and the adoption of credit-based paper money triggered a period of higher growth that eventually led to the industrial revolution).

There's debate on inflation itself, but the economic consensus is in favor of price stability and that's what central bank are targeting. The reason why they are targeting 2% and not 0% is something you can learn from any book or economic resource on the internet, but there's nothing we can do against the fact that you somehow decided never to document yourself on the subject…

Your stance of “I've no idea how the works works or why it works this way and I won't try, but it definitely suck and doing this instead would be better” doesn't make you look good, you know?

Yeah, I’ve seen them. They’re wrong. The point is price levelling is computationally expensive. It can never come for free. If your economy is dynamic—let alone growing—prices will slip. From time to time, they will do so in a generalised form.

I actually think policymakers’ aversion to deflation comes from its intractability. Lots of societies have collapsed before they could solve deflation. Our examples of inflationary shitshows is partly due to their resilience—a deflating society starves fast.

Are there? What were these societies?

If I go to the deflation page on Wikipedia (https://en.wikipedia.org/wiki/Deflation) the preponderance of examples are places that are actually pretty nice to live and as far as I can see have uniformly not collapsed.

Look up Brüning maybe? ;)

I looked him [0] up. They were trying deflation because they'd tried inflation in the 1920s and that, spectacularly, didn't work. The issue at the time seems to have been that old favourite; the Treaty of Versailles. Germany at the time was under what was described as a "Carthaginian peace" by Keynes who took the opinion that it was trying to destroy Germany's economy.

Given that the German economy then failed; I don't think that is necessarily a reasonable example of failed internal policy. It would be reasonable to interpret it as a society burdened with too many debts to foreign powers with no way to recover.

It's fascinating to see how closed minded you are and how it makes you read everything in the way that fit your preconceptions. Feel free to live with your confirmation bias, but then do not wonder why the world seems to be going backward around you ;).
