What you are proposing is an idea of how to make fiat money = toilet paper
Even though they are literally the same still people trust them because they believe that they hold the value of what it say and if you are proposing an idea to break that chain then what actually will be the value of your fiat?
If people can get loans from the government when they want and there is no need to repay it will not increase the value, it makes the value zero so here comes the basic theory of all the demand and supply decide the value of a product.
If there is a product with high supply and no demand the value is zero similarly if a product has no supply but high demand still the value is zero so balancing the part decides the value of every product.
