It's not meaningless if your goal is to steal and that's what that 'article' proposes - theft.
1. Government steals by forcing people to declare all of their cash savings and to justify them to transfer them into the electronic form.
2. Government steals by creating inflation electronically, so it's cheaper and faster for the government to create vast amounts of virtual money and dilute existing savings, thus stealing (creating inflation).
3. Government can steal everything at any time by simply emptying your bank account and leaving you with nothing.
4. Government will steal by setting stupid exchange rates that are absolutely fake, like pegging the exchange say 1USD to 10Pesos while on the 'black market' you would get many times more pesos, for example 100 for 1.
5. Government can control you if you do not have access to your own money, and it can prevent you from doing anything they don't like and punish you for doing anything they don't approve of.
It's a gigantic con, don't fall for it, it doesn't matter what the name of the currency is if you are not even able to have it in your own hands.
Basically if you cannot hold your own money in your own hands but government holds it for you (directly or through proxy banks) you are fucked, you have nothing.
If you try to switch to gold and other currencies of your choice, you will be labeled a 'speculator' and 'enemy of the working class' etc., and you can be dealt with criminally.
