I'm a bit new to crypto, but I find your definition of money to be somewhat faulty. Paper money products have absolutely no value. The only thing that gives them value is a false belief that they are an IOU to be exchanged for a tangible item. They are not backed by anything more than a promise from the people in control of the printing press used to publish the currency. A penny actually has more value than a $100 bill. The penny can be melted down for its copper content, which can then be remanufactured into something useful. A $100 bill is the equivalent of high priced toilet paper, it cannot be recycled into anything of usefulness, and if we quit using it, those in control of it would be absolutely powerless overnight. That is why crypto has such a hard time getting off the ground, people haven't been trained to understand that there are things other than paper to trade for goods and services...future generations will laugh uncontrollably about fiat currencies, but I am not sure we will witness it in our lifetime.
