This is because money is trying to be two things at once - a medium of exchange, and a stable asset - and those are often in conflict.

If I just want to trade my bushel of corn for your chicken, money makes it easier - I exchange my corn for some money, and then I exchange that money for your chicken. I don’t care whether the money is ‘one fricasee’ or ‘ten million gorzebos’ as long as we both agree that’s the number attached to it. You can use something that is a real asset for this, but it actually doesn’t have to have any intrinsic value to be usable for this, as long as everyone agrees to use it.

However, there’s a time element - I can sell my corn, and then keep the money for a while, retaining the power to buy the chicken later. That turns it into a potential asset. During that time, the numbers attached to different items could go up or down - the time element makes arbitrage possible. Even for ‘useless’ assets.

Too much money held as assets can reduce its effectiveness as a medium of exchange - but improving the effectiveness as a medium of exchange can reduce its stability/value as an asset.

Also probably why there is a lot of contention over gold standards etc. - the gold standard improves its value as an asset, while potentially limiting its value as a medium of exchange - so it’s going to depend on which one you prioritize whether you will favor it or not.
