Economies can’t go any further than the labor they can unleash. You can’t fiat labor that isn’t there. You do have to give that labor a reason to work.
As long as everyone keeps believing in the money, even if it is fiat money, they will keep on working. Maybe it is a kind of soft implementation of the socialist ideal of “to each according to his need, from each according to his ability.” The latter one is tougher, but fiat money seems to get around it for now.
Of course this is all from a worldly point of view. Bring theology into the mix and yes you can get supernatural money. Jesus didn’t seem to have a problem with Caesar’s taxes, paid with Caesar’s coins.
Work is freedom.
