Also, QE was undertaken as an attempt to prevent deflation, which is the real enemy of a capitalist economy. If money can grow in value buried under a bed, the incentive to lend disappears. More people were paying back loans than taking them out, even with nearly zero interest rates, which reduces the money supply. QE was a response to that, and a perfectly defensible one.
That's one of the misconceptions here - that money is a thing that is printed by governments. It's not. It's a set of obligations that are created by loans. It's more or less the same mistake that Friedman and the monetarists made - and they soon managed to disprove their theory when they tried to put it into practice and the money supply kept growing. The only difference is that a central bank/govt can essentially lend to itself, which is what QE was in effect.
In some ways, bc resembles gold - hard to get hold of, virtually impossible to alter. In others it doesn't - no aesthetic value whatever, no prestige associated with its ownership or display. Gold rushes were also at root a collective madness in pursuit of a mostly useless endeavour, of course.
As for the fact that the number of bc is limited, that is simply irrelevant to anything, except fuelling the delusional behaviour. If its value doubles, it doubles. If its value halves, it halves. And if its value collapses to nothing, it collapses to nothing. Nothing whatever to do with inflation. The idea that it is a store of value is also absurd. It literally burns value through the mining, and that will have to be accounted for at some point by somebody. Also, if I buy some premium bonds and forget about them for 30 years, then find them at the bottom of a drawer, that doesn't mean the money has done nothing in that time. Buying those bonds put the money right back into circulation. BC isn't like that. If you leave a bc on the ledger, it just sits there, not circulating. That's not money, and it's not storing value because it is not contributing towards the creation of value. It has not created an obligation.
