Not agree with you on this point. Otherwise, let me ask you. When buying something and you pay with coins/banknotes, how are you protected? You can't go to the police and the bank and say my banknote has the number #xxxxx printed on it. As of today, it hasn't been a problem to spread this method of payment. Same thing when gold was used to trade
Yes, cryptos resemble cash. But:
- You don't use cash (or gold) for large "unattended" transactions. Do you buy with cash a 1000 usd / eur product in a dark alley when nobody else is present? In a transaction with other witnesses where the seller claims "You haven't paid for this" I can ultimately seek protection by law. I cannot say
this is my banknote but I can try to prove that I have paid.
- You cannot use cash or gold for not face-to-face transactions.
