Discouraging unnecessary spending and investment is desired for a good society. The fiat debasement which encourages all manner of unnecessary fuckery such as financial engineering, share buybacks etc is not desired.

One could argue about the right amount of monetary deflation and there is nuance there.

Central bankers in the 90s adopted a 2% inflation target but there is zero trust there and also this inflation target is targeting changes in the price of goods and services, not increase in the money supply.

If they had actually adopted a strict 2% per annum cap on the increase in the money supply that would be something but instead everytime humans get more efficient at producing goods and services at lower cost they use that as an excuse to print more money and "target inflation".

That is to say any system which enforces strict limits on the increase in the money supply (on the order of the increase in Gold supply) is preferable to the current unlimited money system in place with the Fiat Standard.
