Maybe you wouldn't mind at all if currency became digital and everyone (rich and poor) was forced to pay their fair share for the common good. Nobody could hoard anything then.
As
AZPaul3 said, currency is already digital. Perhaps you intended that as a reference to crypto-currency. I'm skeptical of crypto-currency.
It is not at all clear what you were really trying to ask. There will always be those who live by theft and fail to pay their fair share toward the common good. And there will always hoarders. That's just human nature. Christianity has not been able to repeal human nature, and humanism won't be able to do it either
