And it is beneficial for them to do so simply because it enables them to spend more without having to take unpopular measures like raising taxes.
I have read the vast majority of the arguments for having inflation or deflation and to be perfectly honest I find most of them to be unconvincing and essentially boil down to "it's good because its good".
Both inflation, deflation and stagflation have their benefits and drawbacks and they all have a place and should all be used, because economic scenarios and circumstances differ over time and place. To state that we should all have at all times everywhere 2% inflation is dumb, dangerous and frankly if you hold that sort of view you have no business being anywhere near monetary policy because you're not an economist, you're a priest.
This is a dangerous narrative. By strictly econometric measures, the 2008 crisis was not too far off of, say, the great depression. By and large, I wonder if the reason why people aren't dying on the streets (aka "chaos"), etc, is because we have reliable sources of food, access to medicine, etc.
It’s fine to think that there might be other, better approaches to solving those problems. It’s fine to argue that central banks might not always act with the best interests of the economy at heart. But pretending like those problems weren’t real and that we don’t need any of it—as the financially-illiterate cryptocurrency community seems to do—is absurd.
