countries with a passionate regard for their nationality and history such as Italy do present an obstacle to the elites who want the power that a global currency linked to one central bank gives them over elected politicians, think how much power the eu comission wield over the eu countries etc.. all those countries lost a bit of their unique identity and self independence when they gave up their currency, lira, franc, deutsche mark etc I can't see how they can ever go back, italians born since 2002 only know the euro.
If the move to a cashless society carries on at the pace so far, then I think in about 20 years, paper notes will cease to be legal tender in the UK. Countries often follow suit, some may be slower to ditch notes like Germany but as more and more transactions with cash are made difficult they will have to switch over for sheer convenience.
The media and politicians will do as they're told and promote a electronic global currency, saying it will help erase world poverty by stopping currency speculation which devalues people's money, it will get rid of crime as there can be no black economy because all income will be traceable, it will save trees and oil to make the notes and mint the coins etc... If you take into account how, in general, the youngsters today are easily manipulated and lead by the mainstream media on 'issues', and that a free and independent internet is also being slowly eroded, any narrative will be difficult to challenge.
Personally, I would rather stick as we currently are with electronic and paper money and if I had my wish I'd bring back all the old european currencies, as you said the countries with poorer economies actually suffered more by joining the euro.
I think the 'elite' believe one global government with one currency will end wars and poverty [think how much money and resources could be saved if there was only 1 smallish central army in the world, all the research and effort developing and making weapons could be spent on medical research, preserving the planet etc..] I'm sure some of the elite believe its their moral duty to bring these changes about.
But if we go down this route and change from a world of independent nations to just one world state, there is no protection against that state becoming totalitarian. [ which the online cambridge dictionary defines as:a political system in which those in power have complete control and do not allow people freedom to oppose them].
