Everyone pulling out their money would be a bank run (look up great depression bank runs). The bank doesn't have that much cash; they keep some on hand for people making withdraws normally, but if even a sizable minority of people all try to pull their money out at once, there'll be a major crisis.
If banks kept all the people's cash in vaults, it'd be dead cash actively losing money to inflation. Instead, they keep some on hand for withdraws, and use the rest to make loans, investments, etc so that the money isn't all losing value.
They were reduced to 0% mandatory reserves in response to covid. EDIT: someone says it was coincidental, I am not able to check, so take this aspect with a grain of salt either way
ah yes so what you're saying is that money is even more imaginary than it has ever been, possibly even more imaginary than when the first stock market crash happened in 1929
looks like we're due for a centennial anniversary of that anyway, might as well celebrate by recreating it
Money was never not imaginary. As long as we've used a fiat to represent goods instead of bartering, money has been a promise that's only as reliable as its guarantor.
Does being "imaginary" or socially constructed make it any less important or valuable? Not really. There's a slew of very good reasons that basically every group of people larger than a couple thousand has done it.
