I disagree.

When I lend 2022 dollars to the government, I give away a certain amount of buying power.

I don't know if I will get that buying power back when I get my 2032 dollars.

The government does not always have the capability to pay me back my buying power. It cannot create value at will. It can create money at will. But the more money it creates, the less value it has. So it cannot create value at will.
