I think its not fair to compare the three, they have their own pros and cons. Yes, it is true that bitcoin may have all the advantages a human need but keep in mind that there are a lot of people who doesn't use any electronics or gadgets. So I guess the diagram is still missing out something.
I don't see any unfairness here because they all serves as a medium of exchange, and yes they each have their pros and cons but btc advantage outweighs any cons from a transparent and secured perspective.
The world is rapidly advancing technologically and those who are still illiterate to electronics will start to gradually learning and understanding how it works, even the fiat system are more of electronic operations this days, online banking is mostly what is happening now.
