> People also don’t realize that moderate inflation is a good thing.
Price stability is a good thing, and moderate deflation (which discourages productive investment) is worse than moderate inflation, so policy targeting moderate inflation is a good thing. This isn’t because moderate inflation is a good thing in and of itself, its because you can’t perfectly target price level outcomes with policy, so you want to bias missing on the less harmful side.

The utility of consumption encourages consumption. To the extent that inflation is good its more as gentle inbuilt mechanism to discourage nonproductive saving of cash in favor of productive investment.
> There’s a reason nobody spends Bitcoin
Right. You definitely don’t want deflation, which encourages hoarding currency that is surplus to immediate consumption desires and thereby sucks money out of productive investment.
