cash-less doesn't mean it will be replaced by cryptocurrencies. and it certainly doesn't mean no government control. and making it into a long wallet of text, bolding and coloring it won't change that!
cash-less means we are going to move on to digital form instead. what we use is not going to change, but only the shape of it. in other words we will still be using the same fiat that we have used for hundreds of years but now with credit cards, with our cell phones, with cryptocurrencies which are centralized and issued by the government and represent the same fiat.
and your title is completely irrelevant to all this.
You are right.Same fiat money would be in the form of digital currency most of which would be issued and controlled by the appropriate governments.This would not give any sort of financial freedom to people.They would still be under the radar of government authorities.
Cashless economy would only benifit common man if bitcoin like crypto currencies get used massively and I don't hope that governments would allow such economic activities to occur unquestioned.
