Point taken. However, another important aspect is that currencies around the wolrd fulfill the same functions whereas when it comes to crypto - each token will represent anything that the creator intended it to be PLUS what the community uses it for (e.g. store of value). And each token will have a different 'design', different functions - from being tokens to enter the platform (e.g. Ethereuem itself) to tokens representing fractual ownership in assets (e.g. Maecenas art tokens or our RAT tokens representing a rat mascot, more about it here: https://medium.com/@katdum/what-did-i-learn-from-tokenizing-...). So there will be coins that will be fulfilling the descirption of a currency (apart from the government requirement) but there will be only a few ones compared to the vast amount of tokens with different functions.
