The barter system was a primitive way of doing things that could hardly be applicable to the kind of commerce we have in this modern times. The large-scale commercial transactions of today cannot be supported by a simple barter system. And that is perhaps how it is being replaced with a more efficient means of doing transactions a long time ago. We used gold, silver, copper, and other precious stones to make things easier.
Printing money out of thin air is a rampant problem. And the solution is not barter. The solution is crypto. There is no cheating or faking in crypto.
I could also see that using the barter system for now is just solving problem with another problem. The fact that crypto is limited supply could bring an end to the massive money printing and therefore saving the whole economy from being overly inflated as well as eliminating any worry that lingers around the people. But, if the crypto being used have a little value and just stuck there, I doubt it will be any better for the whole economy compared to paper money.
The value of crypto will be determined by the people itself. So if it is low, it does not matter much for as long as it is quite stable. Even if the price of Bitcoin will reach stability at around $5,000 or even $1,000, it does not mean to say that paper money is going to be better than it. However low the value of Bitcoin in USD is, it still does not take away the features which makes it a world better than fiat. It remains decentralized, borderless, fairly anonymous, and so on.
