The point is that even if you don't want anything, you still have the potential to spend it, or invest it, or loan it for rent, so it does have value. Now if you want to prove that money has no value, then please send me all of your money, and I will announce to the world that money has no value, and my proof will be that you gave me money for free. Please message me and I will provide you with my paypal account name, you are welcome to send me as much money as you have.
If you are just now figuring out that money is not a good long term storage of value, then you are a little on the slow side. Fiat money is not intended to be a long term storage of value. money sitting in a jar does not help our economy, so our gov purposely deflates the value of our currency, to incentivise the holders of money to invest or to loan, which is somewhat productive. If you had invested that 1957 nickel into something that is a good long term storage of value, and even a creator of wealth, you would likely have enough to purchase a cup of coffee plus a doughnut today.
Those silly asians. Accepting imaginary money for real goods. Thats proof right their that Asians are not nearly as smart as we tend to give them credit for being.
