I don't think this will work because it doesn't mean that people will have more access to jobs or more access to money. Those who work for fiat will work for cryptos, but there will be those who decide to take the evil way. A crypto-based economy is only going to replace crypto with fiat, I assume the same thing is going to happen, the rich are going to stay rich and the poor will remain poor. But crypto will give more freedom to the people.
